A fire broke out in a storeroom of the Samsung Experience Store at AMK Hub shopping mall in Ang Mo Kio early yesterday morning, causing neighbouring businesses a late and waterlogged start to the day.

The fire, which happened at 1.25am at the basement one store, was put out by the mall's sprinkler system and Singapore Civil Defence Force (SCDF) personnel.

An SCDF spokesman said the fire involved contents measuring 1m by 2m in the shop's storeroom.

In response to queries, Samsung said it is assessing the property damage and working closely with the authorities to determine the cause of the fire.

The area surrounding the store was cordoned off and a faint smell of smoke hung in the air when The Straits Times visited the scene at about 10am yesterday.

AMK Hub general manager Andy Kau said there were no injuries, and the basement one area near the Samsung store was temporarily closed to the public to facilitate cleanup efforts. The affected stores had opened by 1.30pm, he said.

Several businesses around the Samsung store spent the morning mopping up pools of water that had formed from the fire sprinklers.

A shop assistant at nearby Nail Palace said part of the salon was flooded when she arrived at 9am, while at the shoe sale opposite, stock kept on the floor overnight was damaged by water.

Furniture retailer Lux Grandeur, which began its week-long bedding roadshow on Monday near the Samsung store, said its 17 bedframes and mattresses were beyond salvage. The roadshow's organiser is in touch with mall management to discuss compensation and refunds, said a Lux spokesman.

Some shoppers were unhappy about the delays. Chief administrator Asmah Devi, 54, headed for the Singtel Shop at about 11am only to find the area cordoned off.

"I took leave to help my husband switch from his 2G phone. Now I have to find another shop," she said.
