Two cars, including an Alfa Romeo, caught fire in separate incidents on Sunday night.

In the first incident, a car caught fire in Tan Quee Lan Street at about 7pm. The Singapore Civil Defence Force (SCDF) said it was alerted to the case at about 7.30pm, and dispatched two fire engines and two fire bikes to the scene.

Members of the public put out the flames using a fire extinguisher before the SCDF arrived, said a spokesman. No one was injured.

In a separate incident, an Alfa Romeo caught fire in Hougang at around 8pm on the same day. SCDF said it responded to the fire, which was at the junction of Upper Serangoon Road and Hougang Avenue 4.

According to Shin Min Daily News, a family was driving towards Hougang Avenue 4 when smoke started coming out from the hood of the car. A couple and their son then exited the vehicle. Videos posted on social media showed tall plumes of smoke emanating from the car, which had its hazard lights on.

The fire was extinguished by SCDF officers using two compressed air foam backpacks and a water jet, said the spokesman.

There were no reported injuries. The cause of the fire is being investigated, said SCDF.
