MONTREAL -- The provincial police say they will not bother to recoup the guns dumped into the St. Lawrence River during the 1990s biker war.

The dump site has strong currents and most of the people connected with the biker war have either been charged or imprisoned, police said.

QMI Agency obtained a federal report that revealed - based on information by informants - that the Hells Angels dumped hundreds of weapons under the Jacques-Cartier Bridge on the eastern edge of downtown Montreal.

The water current under the bridge makes any diving expedition "too dangerous" said provincial police spokesman Michel Brunet.

A diving expert told QMI Agency that the water under the bridge moves at seven knots.
"We can dive in water running at one knot - maximum," said Michel Birs. "There is a reason why they threw the guns there."

Montreal police spokesman Laurent Gingras said that the city could, in theory, search the area for a specific weapon, "but we would have to have specific information."

Between 1994 and 2002, 165 people were killed in the war between the Hells Angels and the Rock Machine over control of lucrative Quebec drug territory.
