Convicted bomb-maker Inderjit Singh Reyat had a bigger role than he admitted in blowing up an Air India jet, a Crown prosecutor told a Vancouver court.

Gordon Matei made the charge Tuesday as he began the Crown's three-week long closing arguments in the case of Ripudaman Singh Malik and Ajaib Singh Bagri, who are accused of plotting to put bombs on two 747 jets in 1985.

One blew up on an Air India flight, killing all 329 passengers and crew, most of them Canadians.

Manslaughter plea

Reyat was jailed after pleading guilty to manslaughter in the bombing.

He has said he didn't know who or what he was building the bombs for.

But Matei told the court that Reyat was much more deeply involved in the conspiracy than he admitted.

Air India Flight 182 left Toronto and blew up off the coast of Ireland on June 23, 1985.

Matei said a second bomb was set to go off at the same time on an Air India flight to Bombay, but it blew up when the bags were routed through Tokyo.

Two baggage handlers were killed.

The Crown alleges that Bagri and Malik targeted India's national airline in reaction to the Indian army's 1984 attack on the Golden Temple, the holiest shrine in the Sikh religion.
