ROCHESTER, N.Y. (WROC) — A lockdown has been lifted at highland hospital after police say a suspicious call came in. Highland Hospital was briefly put on lockdown Friday, after police received what they said was a “suspicious call.”

The Rochester Police Department received a 911 call claiming a potentially armed person was outside the hospital standing near a car.

Hospital security put the building into lockdown “out of an abundance of caution.”

Police said the hospital grounds were checked and cleared by RPD, and the unknown individual was not found. They said hospital security would lift the lockdown shortly after 4:30 p.m.

Police are treating the investigation as a suspicious call. Officers will remain stationed around the hospital.

Patient Care Tech, Alexis Ramos, says as time passed her fear grew.

“In the beginning I wasn’t as scared but the more they started issuing more restrictions on the floor that’s when I got a little worried and I text my dad to let him know where I was. So, we were all in lockdown to the point where they issued stop patient care because it got that crazy,” Ramos said.

RPD said no one was ever located but they would continue special attention around the hospital.
