What is VSC?
The Volunteer Special Constabulary (VSC) was formed in 1946 to provide support to regular police officers.
The scheme now requires volunteer recruits to undergo a non-residential basic course at the Police Academy twice a weekfor six months.
The course covers areas such as basic legal knowledge, firearms training, drills, and police defence tactics.
There are about 800 VSC officers in Singapore, The Straits Times reported last year.
VSC officers have the same power as police officers and wear the same uniform. They also patrol the streets and take part in operations.
A police spokesman said Koon Kok Wai , who joined the VSC in February 2006, was discharged from service in July 2014 following his arrest in late June that year.
"VSC officers who commit offences can expect to be charged in court and dealt with in accordance with the law," the spokesman said.
