SINGAPORE – Four women were taken to the hospital and a bus driver was arrested after an accident involving buses of two public transport operators at Boon Lay interchange on Dec 29.

The buses involved were running SMRT service 178 and SBS Transit service 199.

In response to The Straits Times’ queries, the police said they were alerted to the incident at 61 Jurong West Central 3 at 9.10pm on Dec 29.

Four female bus passengers, aged between 40 and 77, were taken conscious to the hospital. The Singapore Civil Defence Force said they were taken to Ng Teng Fong General Hospital.

A 56-year-old male bus driver was arrested for a negligent act causing hurt, the police added.

SBS Transit spokeswoman Grace Wu told ST that bus service 199 was stationary when it was hit by bus service 178, which was moving off from the boarding berth.

She added that there were no passengers on board the SBS Transit bus and its driver was not hurt.

SMRT Buses deputy managing director Vincent Gay told ST that the accident happened at about 8.55pm.
