Lawrence police called in assistance for possible explosives that officers found during a search of a home Monday, according to a department spokesperson.

Officers were executing a search warrant at a home near the intersection of Kasold Drive and Harvard Road when they found what they believed could be “unexploded military ordnance,” said Patrick Compton, spokesperson for the Lawrence Police Department.

Officers called for assistance from Fort Riley, Compton said. Department policy states that officers should not touch or move suspected explosive devices, but rather call a bomb squad or military explosive ordnance disposal team.

No one was injured in connection with the incident, Compton said, and no residents of nearby homes were asked to evacuate the area.

A man was arrested at a home in the 1100 block of Kasold Drive at 1:20 p.m. Monday on suspicion of aggravated assault, criminal possession of a weapon by a felon and criminal threat, according to the Douglas County Jail booking log. The arrest was in connection with an associated disturbance with weapons call LPD received early Sunday morning, according to Compton and department and jail records.
