There was another swarming in Halifax early Saturday morning as a group of male teens beat two men with tree limbs, police say.

Two males were walking north on Robie Street at the intersection with Oakland Street in the city's south end at 1:30 a.m. AT when they were approached by five males, all apparently in their late teens, Halifax Regional Police Sgt. Kevin McNeil said Saturday.

The two groups got into an argument, he said, and then the attack began.

"The two victims continued to walk up Robie Street when one of them was struck on the back of the head with a tree limb. The group of assailants then began to punch that male in the face," McNeil said.

"The second male with him was knocked to the ground and he was also kicked and punched in the head area. All parties ran from the scene."

One teenaged male is in custody in relation to the incident, he said, and will be charged with assault.

McNeil said the attack was random. He wouldn't say whether police think it is related to seven swarmings in central Halifax, near the Halifax Common, that began over the Labour Day weekend.

In each of those cases, a group approached the victims by asking for a cigarette or a light, then beat their prey. Some of the victims were robbed.
