LANSING, Mich. (WLNS) — According to Lansing police, Sparrow Hospital is no longer under lockdown after several threats were directed towards the building.

Lansing police said officers were dispatched to the hospital around 3:31 a.m. for reports of a person with an AR-15. Officers immediately responded and received more calls from the same person threatening to bomb the building.

Officials say officers then searched the building and determined the threats were not credible. The building was given the official all-clear at 6:29 a.m.

LPD said they believe the threats were “swatting calls,” which is when people report fake serious crimes to emergency services.

At this time, police do not have a suspect, but they do not believe there is a threat to the public.

“We take swatting calls like these very seriously and we continue to investigate to try and find out who is responsible,” LPD said on social media.

Early Monday morning, there was a heavy police presence surrounding Sparrow, and Lansing police told 6 News that the hospital was on lockdown. Our crew on the scene could see multiple police agencies and some officers directing traffic away from the area.

Hospital employees could be seen waiting in the parking lot of the building.
