Halifax Regional Police are searching for a "rugged looking" man believed to have broken into vehicles Saturday morning on Herring Cove Road.

Police received a call reporting the break-ins on the 100 block of Herring Cove around 10:15 a.m., according to a statement from Staff Sgt. Bill Morris.

The man, thought to be in his 20s, was stopped by a construction worker, Morris said. The man then pulled a knife and ran away.

A K9 unit tried unsuccessfully to track him down. Instead, the unit found a couple items it believes were stolen from the vehicles.

The suspect is described as having rotten teeth, acne and being "rugged looking, with neck tattoos," the release said. He was wearing black sweat pants and a black hooded sweatshirt with red on it.
