CLIFFSIDE PARK — Two borough special police officers on patrol were struck by a sports utility vehicle Saturday, leaving one severely hurt with a head injury, authorities said.

The uniformed officers, both 22-year-old men, were taken to Hackensack University Medical Center, according to borough spokesman William Maer. One officer was in very serious condition and undergoing surgery while the other was listed in serious, but stable condition.

Bergen County Prosecutor John L. Molinelli said the county's Fatal Accident Investigation Unit was assisting local police in the probe.

"Two special police officers were crossing the street and struck by [a] female driver," Molinelli said in an email Saturday night. "One officer [has] minor injuries, the other officer has what appears to be a significant head injury and is unconscious."

Maer said the officers were struck on Walker Street around 6:30 p.m. by a Honda CR-V sport utility vehicle. The circumstances surrounding the accident remained under investigation, he said.

The driver of the car who struck the officers was being questioned by police, according to Maer. No charges have been filed against the Cliffside Park resident.

Thomas Calabrese, the borough's acting mayor and council president, said the officers were on a routine patrol when they were struck.

"The thoughts and prayers of all the residents of our municipality are with the special officers and their families," Calabrese said in a statement. "These are two brave individuals on routine foot patrol making sure the residents of Cliffside Park are safe and secure."

The injured men were working as Class I special officers, meaning they are unarmed and have limited law enforcement powers, officials said.

Special police officers generally work part-time to support fully-sworn officers and some carry weapons with differing police authority.
