A SOUTH-BOUND train carrying about 200 passengers was evacuated at Toa Payoh MRT Station on Thursday after smoke was seen in one of the carriages.

An SMRT spokesman said that smoke was detected coming from an air-conditioning unit at the rear of the train at about 1.25pm.

The train was removed from service and regular operations resumed in about seven minutes. No one was injured.

SMRT is investigating the cause of the incident.
