Five teenagers are accused of assaulting a group of people with fire extinguisher foam early Monday morning, say Halifax Regional Police.

Investigators said a car was pummelled with eggs at the corner of South Park Street and Victoria Road at about 12:20 a.m.

When the people in the car rolled down their windows to confront the egg throwers, officers said they were sprayed with the foam.

The five teens — all 16 years old — were found nearby. They face charges of stealing the three fire extinguishers as well as mischief and assault.

They've all been ordered to appear in a Halifax youth court at a later date.

Staff Sgt. Barb Saunders said she's never heard of a fire extinguisher attack.

"Personally, no, I have not," she said. "I don't know if it has been used before or not."
