Investigations revealed that Achchha, who is presently in the custody of police, hails from Olpad taluka of Surat district. He had moved to Canada in 2002 and claimed to have become a citizen in 2014, Mr Patel said.
"We recovered a Canadian passport from him, which established that he holds the citizenship of that country.
The passport was issued in 2014. He lives in Mississauga city there with his family. Investigations have also revealed that he overstayed here, as his visa had expired in January," Mr Patel said.
On the day of his arrest, police had recovered one pistol and a stolen bike from him. Later, police found two more pistols, 16 cartridges, one extra magazine and two more stolen bikes, the officer added.
"His brother was murdered in 2002. Later in 2007, he had an altercation with the murder accused. Achchaa claimed that he acquired these pistols for his self-protection," Mr Patel said.
Probe is on to find out his possible links with any other anti-social elements, the officer said.
