Four people suffered non-life-threatening injuries in an accident Wednesday night involving a SEPTA bus and another vehicle near the King of Prussia Mall.

The accident occurred about 9:15 p.m. in the 600 block of Allendale Road, a Montgomery County dispatcher said.

SEPTA said the accident caused the Route 125 bus to crash through a guard rail and down a small embankment into some trees.

The four injured people were transported to a local hospital, the dispatcher said. SEPTA said three of the injured were on the bus.

The cause of the accident — and if it was related to the rain storms that passed through the region — was under investigation.
