MUAR, MALAYSIA - A 65-year-old man on his way to Singapore to attend his son's wedding ceremony died in a bus crash on Malaysia's North-South Expressway early on Monday (Dec 5) morning.

The accident occurred at about 3am on the North-South Expressway, towards Muar district's Pagoh town from Tangkak district, Lianhe Wanbao reported on Tuesday (Dec 6).

The bus had been carrying 27 passengers from Malaysia's north-west Perak state to Singapore when it allegedly swerved to avoid a trailer in front of it and lost control, crashing into the back of the trailer.

The impact left the front of the bus mangled. According to the bus driver, a plank from the trailer had dislodged and smashed into the bus, striking Peng Huafa, who was seated behind the driver.

Mr Peng had been with his niece on their way to his son's marriage registration ceremony.

His niece and another female passenger fractured their legs in the crash.

Firefighters at the scene rescued injured passengers from the vehicle, but Mr Peng was certified dead on the spot.

Mr Peng's niece, who did not give her name, said she was sleeping when the accident occurred, Wanbao reported.

The great impact woke her up and she was shocked to find that her uncle had been struck by a plank.

She added that the bus had been travelling "very quickly", and that there were no relief bus drivers on board.

Muar traffic police detained both the bus and trailer drivers for investigations.

After the accident, three men allegedly looted the bus, stealing an iPhone 7 from Mr Peng's niece and the money from Mr Peng's wallet, Shin Min Daily News reported.

Mr Peng's son postponed his wedding and rushed to Perak for the funeral.

His mother had died two years ago, and he works in Singapore with three other siblings.

He was the first of his siblings to be married.
