(CNN) -- An alleged Israeli agent will be extradited to Germany to be tried for spying, the Polish court of appeals press officer told CNN Thursday.
The alleged agent "is accused of helping to get false documents for the man who is thought to have killed the Hamas leader in Dubai," the officer said.
The man was arrested in Poland two months ago on a European warrant in connection with the procurement of a false German passport, as part of an investigation into the killing. German authorities then requested the man's extradition.
Mahmoud al-Mabhouh, a founding member of Hamas' military wing, was found dead in January in his hotel room in Dubai. Police believe he was killed the night before and suspect the Mossad, Israel's foreign intelligence unit, was behind the assassination.
Several countries such as Ireland, the United Kingdom and Australia have kicked out Israeli diplomats after concluding Israel had probably forged their countries' passports as part of the operation.
Israel has maintained there is no proof linking it to the doctored passports or the killing of al-Mabhouh.
Israeli Foreign Minister Avigdor Lieberman told Israel Army Radio in March that there is certainly no reason to think that the Mossad and not some other intelligence agency of another country operated there.
Dubai police have identified a total of 33 suspects in the case.
Most are believed to have acquired fake passports to go to Dubai for the killing and then fleeing to far-flung locations, police said.
The suspects used British, Irish, French, Australian and German passports. In February, the European Union condemned the use of false EU passports in connection with this case.
Police in Dubai said toxicology results show al-Mabhouh was injected with succinylcholine, a drug used to relax muscles during surgery or as an anesthetic, before he was suffocated.
There were signs that al-Mabhouh resisted as he was being killed, police said.
