A Mississauga father charged with murder in the death of his 16-year-old daughter has had his charge upgraded.

Muhammad Parvez, 57, is now facing first-degree murder, Peel Regional Police said on Tuesday.

Parvez was originally charged second-degree murder in the death of his daughter, Aqsa.

She died in hospital on Dec. 10 after police said a man call 911 and said he had killed his daughter.

An autopsy showed Aqsa died from "neck compression."

The teenager had been staying with friends due to a falling out with her family but returned home before school on the day she was killed.

Friends of the teenager said she had been involved in a family dispute over her choice not to wear a hijab, the traditional Muslim head scarf.

Police have not commented on a motive or how the girl was attacked, or the reason why the murder charge was upgraded on Tuesday.

Aqsa's brother, 26-year-old Waqas Parvez, is charged with obstructing police in their investigation into her death. He is free on bail and his case is still before the courts.
