(CNN) -- Canadian police arrested three people Sunday in connection with a daring helicopter escape from a Quebec prison.
Benjamin Hudon-Barbeau, one of two escaped inmates is in custody, along with two other people, said Quebec provincial police spokesman Benoit Richard.
Dany Provencal, the second inmate, is "surrounded," and authorities are negotiating to bring him in peacefully, he said.
"I can tell you one thing: The two people that were inside the jail needed help to get out," Richard told CNN.
The spokesman declined to identify the other two people arrested. He also declined to say where the arrests took place, under what circumstances, or where Provencal was located.
The three people arrested will appear in court Monday morning.
The escape happened at around 2:20 p.m. ET Sunday at a prison in Saint-Jerome, northwest of Montreal.
The pilot was taken to a hospital for examination and will be interviewed by investigators, Richard said. He did not know whether the pilot had been injured and declined to speculate on news reports that said the inmates held a gun to the pilot's head, forcing him to fly.
Richard told CNN the pilot is considered a witness, not a suspect.
Hudon-Barbeau was cleared on appeal of a double murder, but returned to prison in connection with an attempted murder investigation, the spokesman said. He said he did not know what Provencal was convicted of.
Christa McGregor, spokeswoman for the Correctional Service of Canada, said Provencal was serving a federal sentence of seven years and 10 months for various offenses including arson, break and enter, forcible confinement, unauthorized possession of a firearm, utter threats to cause harm and dangerous operation of a motor vehicle.
His sentence started in September 2011, she said.
After the escape, a man claiming to be Hudon-Barbeau spoke to a reporter at 98.5 FM in Montreal, by phone.
"I don't want to cause any harm to anybody. I am not a killer. I never did anything bad to an innocent. I know that (the escape) wasn't the best thing to do, but I didn't want to stay in prison anymore. I am ready to die," the station reported he said.
It also reported that the helicopter involved approached the prison and dropped a cable that allowed the inmates to escape. The helicopter was later found at Mont-Tremblant, also in Quebec.
Once the helicopter landed, Hudon-Barbeau and Provencal are believed to have left in a car. Authorities were looking for that car, but Richard declined to provide a description of it. After the arrests, he said he didn't know whether the vehicle had been found.
Officials were doing a headcount at the prison to make sure that no one else was unaccounted for, the spokesman said.
