Several adults and children were threatened at gunpoint by two men who entered a residence Wednesday in the 1100 block of Pennsylvania Street and searched for possessions.
The home invasion, still under investigation by Lawrence police, occurred about 9:30 p.m.
According to Lawrence police Sgt. Damon Thomas, two men entered the house armed with at least one gun and possibly other weapons and ordered all the people inside to stay to the ground.
The men, who had garments obscuring their faces, then went to a room in the back of the house and rummaged through several possessions before leaving.
Thomas said police weren't sure late Wednesday what the men took, aside from cell phones belonging to some of the people inside the house.
No one was injured.
Police allowed people back inside the house about 11 p.m. but continued to search in and around the house for clues.
Thomas said police didn't know yet whether the victims knew the men.
