Police say there could be more arrests following Thursday's swarming incident in N.D.G.

Sabah Youness has a terrible headache, a cut lip, a bruised back, and a sore leg after being attacked by a mob of teenagers.

Somehow he feels lucky.

"Me I have second life today," said Youness.

The samaritan says he was walking in the alley behind his apartment when he noticed the teenagers throwing rocks at a woman on her balcony.

Youness involved himself in the altercation, and before he knew it, the teens swarmed him.

"They jump on me a lot of guys, then I try to survive and try to run away from them but I can't," said Youness. "They are so many, they have the rocks in the hand."

Youness was pummelled with rocks, sticks, and a toilet lid for trying to help a neighbour.

But the neighbour, who wishes to conceal her identity, has a very different story.

"There were no rocks thrown on me," she told CTV reporter Rob Lurie.

She says Youness was trying to break up a fight between the youths and someone else.

"Eventually I saw them fighting, that's all I saw and I ran in there and called 911," she said.

Whatever happened, the nearby school doesn't like it

"We're in a state of shock," said Robert Mathieu of St. Luc school. "This is not a violent school. We work hard to prevent violence here."

Two 14-year-olds are now under arrest.
