A motorcycle burst into flames moments after it allegedly skidded along Mandai Avenue on Monday (Jan 24) morning.
In a video clip that emerged online hours later, the motorcycle occupying the middle lane was suddenly engulfed by the blaze. A silver Mercedes could be seen manoeuvring around the fire.
According to a passer-by, a male motorcyclist was lying on the road about 30 metres away from the vehicle.
She told Shin Min Daily News that she saw a female motorcyclist pulled over by the side, appearing to be making a phone call for help.
The police and the Singapore Civil Defence Force (SCDF) said they were alerted to the incident at about 7.40am.
SCDF put out the fire with a water hose reel and said the cause of the fire is under investigation.
The 52-year-old male motorcyclist was conscious when taken to Khoo Teck Puat Hospital. He is assisting investigations into careless driving, said the police.
