Halifax Police say a second teen has been arrested in connection with Thursday’s shooting on a Metro Transit bus.

Shots were fired around 1 p.m. on a bus in north end Dartmouth as it travelled through the Pinecrest Drive area.

Police say three teens, two male and one female, got into a fight on the bus and one of them pulled a gun.

The bus was pulled over at the time the shot was fired, as the driver had told the teens to break it up. Police say four other passengers were onboard.

All three fled on foot before police arrived, but surveillance footage from the bus was immediately used by police to identify the trio.

A 16-year-old boy was taken into custody a few hours after yesterday’s incident and was held overnight. He’s facing a number of weapons charges.

An 18-year-old man was arrested last night in Dartmouth and was also held in custody.

He’ll be appearing in court this morning on charges including assault, creating a disturbance and breaching court orders.

Police are still looking for the female, 17, involved in the altercation. Police say she’ll be facing assault charges.

She’s described as black, with short black hair that was in a ponytail at the time. She was wearing a red jacket.

Const. Pierre Bourdages told News 95.7′s Maritime Morning , the investigation is still ongoing and no weapon has been recovered. He said evidence was collected from the bus to indicate a shot was fired.

Bourdages said the passengers and bus driver are doing fine, although the event was understandably traumatic for them.

Investigators are looking to speak to anyone who was in the area at the time.
