US authorities have been trying to keep weapons out of schools

At least four people have been injured in a shooting at a high school near Baltimore, in the US state of Maryland.

Several of the victims have been taken to hospital, at least one with life-threatening injuries, police say.

Witnesses told police a dark-coloured car pulled up outside Randallstown High School. The driver got out and opened fire before driving off.

A car matching the description had been found nearby and a man had been taken into custody, police say.

A charity basketball game designed to raise scholarship money and attended by state legislators was being held inside the school when the shooting occurred.
