UPDATE: Osborne Elementary was placed on lockdown for about an hour Thursday afternoon as police searched the area for three men who were possibly armed.
A Barker Street woman called police at 1 p.m. after she noticed three suspicious men walking outside, according to a Sandusky police report.
The woman said it looked as if one man slid a shotgun down his pants in an attempt to hide it, the report said.
Sandusky and Perkins police and Erie County deputies established a perimeter and searched the area for the suspects. They were unable to locate anyone, although they later learned the suspects may have entered a home in the 600 block of Camp St., the report said.
When officers went to the building, other witnesses told them the men were escaping through a window, Sandusky police Lt. Mike. Campbell said.
Officers continued to search the area but were unable to find them.
Detectives soon descended on the house to process the evidence inside, Sandusky police Detective David West said. Inside they found more than one weapon that did not belong to the homeowner. They also found other items that did not belong to the resident, but police would not say what items they seized.
No one was arrested, and the incident remains under investigation.
The lockdown at Osborne Elementary was lifted just after 2 p.m., allowing children to leave at their normal time, according to a Sandusky Schools press release.
