WATCH: Border crossing bust takes 30 handguns off Toronto's black market

Toronto police say they seized 30 handguns and more than 13 kilograms of marijuana following an investigation into cross-border gun smuggling.

Deputy police chief James Ramer says the probe came to a head when a woman was caught at the border late last month allegedly trying to smuggle 25 of those guns into Canada.

He alleges she had concealed them in the gas tank of her rental car, fully submerged in gasoline.

Ramer says the woman's arrest led them to three other suspects, who are facing firearms and drug trafficking charges.

They say investigators seized the rest of the guns, 136 rounds of ammunition, 166 grams of powdered cocaine and 111 grams of crack cocaine, along with the marijuana.

Police allege the guns had been legally purchased in the southern United States, and would have been sold to gang members in the Greater Toronto Area.
