SINGAPORE: Singapore police have questioned nearly 4,000 foreign workers in a widening crackdown following the city-state’s first riot in more than 40 years, officials confirmed Wednesday. Three more Indian nationals were charged in court on Wednesday with rioting, in addition to 24 compatriots charged a day earlier with the same offence, which is punishable by up to seven years in jail and caning. An estimated 400 South Asian workers went on the rampage on Sunday night after an Indian construction worker was struck and killed by a private bus in a district known as Little India, leaving 39 police officers and emergency responders injured. A police spokeswoman told AFP that so far 176 men including those placed under arrest had been taken to a police complex to have their statements recorded. Around 3,700 foreign workers living in dormitories have been interviewed on site as well, she said.
