Four high-powered rifles were among nine illegal weapons and a quantity of ammunition seized by Operation Kingfish yesterday.
Two shotguns, an M-16 Rifle, two 9mm pistols and 383 rounds of assorted ammunition were also reportedly seized.
The discovery was made at the Kingston Wharves, and the weapons reportedly found in the seat of a sofa after the police suspected that something was wrong with the item.
One woman has reportedly been questioned in connection with the find.
The police were reportedly on operation at the wharf from Wednesday.
Spokesman for Operation Kingfish, Inspector Steve Brown, made a special appeal to persons within the tri-state area of North America.
This, after he disclosed that the guns were believed to have been shipped from there.
As he condemned the motives of persons who migrate to North America and send guns back to Jamaica, Inspector Brown asked: "What are you contributing when you send these guns?" He added: "These guns are sent by Jamaicans to kill Jamaicans. Sending guns back to Jamaica doesn't help in anyway."
