STOMPer Ragu said the fire which spread to three shop houses at Arab Street early this morning (Aug 10) might have been caused by a lit cigarette.
"At about 3am, one of the shop houses along Arab street caught fire.
"The staff started rolling out a long pipe and spraying water.
"Shortly after, the fire engine arrived and started doing their job but by that time, it seems the fire had spread to 3 shops!
"Rumour has it that someone might have deliberately flicked a cigarette into the shop.
