KUALA LUMPUR, July 24 -- A crash among three front-riding motorcycles triggered a massive 15-bike pile-up involving a car and a lorry that killed three riders early this morning, police said.

Seremban district police chief ACP Mohamad Hatta Che Din said the accident occurred around 2.30am at KM 262.5 on the northbound lane of the North-South Expressway in Seremban.

All 15 motorcycles had been travelling together in a group from Senawang towards Kuala Lumpur.

The first collision caused the riders to fall on the highway, leading to a domino effect behind them.

Twelve motorcycles failed to avoid the crash site and collided into the fallen bikes.

Some of the motorcycles also struck the rear and right side of a passing car and a lorry.
