SINGAPORE - At least two Singaporeans were stabbed at a night club in Ho Chi Minh after one of the men bumped into a stranger while dancing, Vietnamese reports said.

Three Vietnamese suspects - Duong Cong Trang, 29; Duong Minh Luan, 19 and Nguyen Hoang Duy, 19 - were arrested on Wednesday (March 9), dtinews.vn reported.

The tourists were at the DC Club in the Vietnamese city's Cong Quynh district on Feb 27 when Singaporean Tan Chee Boon bumped into Trang, said the report.

Vietnamese police told reporters that Mr Tan did not immediately apologise.

Trang then approached the table where Mr Tan was sitting, and suddenly stabbed him with a dagger.

The other two suspects joined in the fray with glasses and bottles, the report said.

Mr Tan's friend Shi Zhi Xiang was stabbed in the head with the same knife while attempting to help his friend, according to dtinews.vn.

Some local reports said that a third Singaporean was also injured.

The Singaporean men were taken to a local hospital by the club's security guards, while their attackers fled.

The police detained Trang first and later arrested Duy and Luan, following Trang's statement.

The investigation is still underway, dtinews.vn said.

Other reports said that the Singaporeans have been discharged and returned to Singapore on March 2.

Singapore's Ministry of Foreign Affairs (MFA) said that Singapore's consulate-general in Ho Chi Minh visited a Singaporean who was hospitalised and kept the next-of-kin informed.

Consular assistance was given to the affected Singaporeans, MFA said.
