CALDWELL, NJ — Caldwell Police trying to serve two arrest warrants on a Caldwell resident were held at bay by the man for several hours on April 11. The standoff lasted nearly four hours, according to police, with the New Jersey State Police TEAMS Unit requested to respond and assist.  

According to police, Caldwell officers and detectives from the Glen Ridge Police Department attempted to serve the two warrants, which originated in Glen Ridge on Michael Rosiak, 58, in a Bloomfield Avenue residence just after 3 p.m.

While attempting to serve the warrants, police said Rosiak opened the shades to the front door and verbally threatened to kill the officers while tapping a large knife on the window of the front door. Police said he also yelled at the officers, stating that he had something for them inside.

Rosiak refused to exit the building, despite police phone contact with the suspect encouraging him to do so. Officers secured the immediate area with a perimeter and removed all civilians from that zone to ensure their safety. Police also closed Bloomfield Ave. between Mountain Ave. and Elm Rd. for the duration of the incident.

The NJSP TEAMS Unit responded and took Rosiak into custody at 6:23 p.m. 

Rosiak was charged with multiple criminal offenses and transported to the Essex County Correctional Facility. 

"I would like to commend my officers and the members of the surrounding departments, specifically the North Caldwell PD, Fairfield PD and the NJSP for their high level of professionalism and calmness during a very difficult and challenging incident," said Caldwell Police Chief James Bongiorno. "It was due to their training and quick thinking that this very volatile situation ended without anyone being injured."

The Chief also expressed his thanks to borough residents for their patience as the incident unfolded and Bloomfield Avenue was closed to vehicle and foot traffic.
