(CNN) -- The Bahrain Grand Prix is threatening to overshadow the Formula One season for a third year running as the kingdom's government and leading human rights organisations dispute the recent arrests of up to 70 people.
In 2012 days of anti-government protests failed to halt the Bahrain GP which went ahead even as nearby streets were blocked with burning tires and trash.
Protests in Bahrain started in February 2011 spurred by uprisings in Tunisia and Egypt.
But demonstrations in Bahrain failed to gain the traction of other Arab Spring uprisings after a crackdown by authorities in the island state.
The crackdown was backed by troops from nearby Saudi Arabia and the United Arab Emirates under the banner of the Gulf Cooperation Council.
The Bahrain Center for Human Rights told CNN Arabic that 20 people from the Dar Klaib and Shahrakan villages -- both near the Bahrain International Circuit -- had been arrested, with another 50 arrested from the Aldeir and Samaheij villages near to the airport.
The Bahrain Centre for Human Rights described the government arrests as "attacks carried out by the security authorities", with BRAVO (The Bahrain Rehabilitation and Anti-violence Organization) president Nada Deif specifically linking them to the April 19 GP.
"Most of the detainees are activists in the fields of journalism documenting and photography," said Deif.
"This latest crackdown and the way it's being carried out raises new questions about the Bahraini authorities' commitment to reform," said Sarah Leah Whitson, Middle East director at Human Rights Watch (HRW) on the organisation's website, which reported police have conducted up to 30 raids in on towns close to the F1 circuit and the roads leading to the capital, Manama.
"These raids and detentions suggest that officials are more concerned with getting activists out of circulation for the F1 race than with addressing the legitimate grievances that have led so many Bahrainis to take to the streets."
However, the Bahrain government insisted the arrests were not linked to the GP.
"The recent arrests came after a terrorist assault on the Foreign Ministry building using Molotov bombs," the Bahraini communication minister and government spokeswoman Samirah Rajab told CNN Arabic.
"Their arrest came under the rule of law and they were sent to Public Prosecution office ahead of their trial. It has nothing to do with the F1 race.
"It's the state responsibility to protect its people along with those who are living in the county and impose security. Also the security forces implement law when arresting someone and don't raid houses unless it has an order from the court of public prosecutor.
"The comments written by HRW are at best secondhand observations made without evidence. HRW is not on the ground in Bahrain to make such comments without verifying its source."
Last year opposition calls for large protests had raised fears the Bahrain GP would have to be canceled for a second year in a row and pose a threat to F1 crews, workers, and fans.
Anti-government protesters had called the race a publicity stunt by the country's rulers to make the nation appear more unified.
F1 is the world's most popular motor sport, and races have a TV audience of more than 500 million, though the scenes last year in Bahrain were viewed as a public relations disaster for both the sport and the country's authorities.
In 2011 the Grand Prix was canceled completely after drivers including former F1 star Damon Hill raised concerns following the death of at least 35 demonstrators as the government called in Saudi Arabian-led forces to help stamp out unrest.
Canceling the race in 2011 cost Bahrain an estimated $480 to $800 million in potential investments.
Bahrain's Sunni-ruled government crushed the Shiite protests, though the opposition has continued to demand political reform in protests and, occasionally, clashes with authorities.
Earlier this week Hill called on the F1's ruling body the FIA and its president Jean Todt to come up with a definitive position on this year's race.
"The vast majority of people in the sport would like to say we don't want to come here to make life worse for people," Hill, who now works as a motorsport television pundit, was quoted as telling a number of British newspapers after a security briefing in Westminster in London.
"We would like you to enjoy F1. It has lots of positive things to offer. But please don't, on our behalf, round people up and brutalize them. I don't see that being political. It's more ethical than political."
Neither the FIA nor Todt were immediately available for comment.
"The messages I'm getting from various people in the opposition -- and there have been pretty regular street protest over the past three weeks -- is that the F1 race will be more of a focus than it was last year," British MP Richard Burden, who chairs parliamentary groups on motorsport and who was outspoken against last year's race taking place, was quoted as telling the Guardian newspaper:
"That's what they anticipate happening. If anything happens it will be a tragedy for all concerned.
"I hope in the next few days that people will understand that words do have an impact."
Bahrain plays a key strategic role in the Middle East and is home to the U.S. Navy's Fifth Fleet headquarters.
