B.C. Liberal MP Ujjal Dosanjh says police should be investigating a Sikh parade in Surrey last month that featured a photo of Talwinder Parmar — the man believed by authorities to have been the mastermind of the Air India bombings.

At the Air India trial, the Crown, defence and judge all agreed that Parmar was the leader of the plot, which claimed 331 lives in 1985.

Parmar came to B.C. in 1970 and lived in the province for more than 20 years before returning to India. Indian police say they killed Parmar in a shootout in 1992.

Surrey's annual Vaisakhi parade was attended by Conservative, Liberal and NDP politicians and included Parmar in its display of Sikh martyrs and saints.

There were also several young people wearing International Sikh Youth Federation T-shirts.

Dosanjh told CBC Radio Friday that those aspects of the parade were unacceptable and that police and politicians should be paying more attention.

"I'm speaking out because I believe that the RCMP and the police forces ought to be looking into these things.

"We need to send a message that parades for diversity are wonderful, differences of opinion are great in this country but any support, direct or indirect, of terrorism or violence would not be acceptable."

Parmar's group, Babbar Khalsa, and the International Sikh Youth Federation are banned in Canada for alleged terrorist activities.

Dosanjh has recently been speaking out about the Air India investigation as well. He said police and governments didn't pay enough attention in the 1980s to the Sikh community.

He suffered a severe beating when, in 1985 as a young Vancouver lawyer, he spoke out against militancy in the Indo-Canadian community.
