Police have arrested a second person in connection with a shooting that injured two young girls in Winnipeg's West End.

A 19-year-old has been charged with attempted murder and several weapons-related offences.

A 14-year-old boy was arrested Thursday and has been charged with aggravated assault and failing to comply with court conditions from a previous arrest.

He remains in custody at the Manitoba Youth Centre.

Shots went through the front window of a house at 542 Victor Street around 6 p.m. Wednesday, hitting a 10-year-old girl playing inside.

Her eight-year-old sister suffered superficial injuries as a result of flying debris, police said.

The 10-year-old is in stable condition in hospital with non-life-threatening injuries.

Police chief Keith McCaskill said the shooting was not a random act but the girls were not the intended targets.

He said the 19-year-old was outside, near the home when he started shooting at another person on the street.

A stray bullet went into the house where the sisters were playing.

Shooting was retaliation: police

McCaskill said the shooting was in retaliation for a fatal shooting Tuesday afternoon on neighbouring Toronto Street.

Until now, police did not believe the two incidents were related.

Kyle Earl, 16, was sitting on the front porch of a home at 646 Toronto St. when two armed people started firing at them Tuesday afternoon.

Earl was hit in the upper and lower body and died. The 13-year-old was hit in the leg and survived.

The 19-year-old was also at the house at the time and chased after the alleged gunmen.

According to police, he started shooting on nearby Agnes Street, hitting two cars, neither of which was connected to the incident.

No one inside the vehicles was hurt.

The 19-year-old was on Victor Street Wednesday and fired more shots, one of which went into the home of the girls, police said.

No arrests have been made in connection with Earl's death or the shooting of the 13-year-old.
