A woman suffered cuts to her head and limbs after she was knocked down by an electric-scooter rider in Bukit Panjang on Tuesday night.
The police were alerted to an accident involving an e-scooter rider and a pedestrian on a pathway in Fajar Road at 10.12pm.
Facebook user Jenn Low, who identified herself as the woman's sister, said in a post on Wednesday that the rider later fled the scene. She appealed for witnesses.
Ms Low said her sister was knocked down from the rear by the rider near Block 442 Fajar Road, while walking to Fajar Shopping Centre. Her sister landed on a grass patch and injured her right temple, arm and leg.
Photos in her Facebook post show bloody cuts on her sister's arm and leg.
"The rider did not stop or provide any assistance. Instead, the rider fled the scene, going towards the direction of Fajar Shopping Centre," Ms Low wrote.
Accidents involving personal mobility devices on public paths have continued to rise, with 128 cases last year. The Land Transport Authority has stepped up enforcement by patrolling areas with a high volume of pedestrians and cyclists.
