A detective Police constable has been charged for allegedly conspiring to pervert the course of justice by staging drug arrests.

He will appear at Kowloon City Magistracy tomorrow.

The charge alleges that between June 7 and December 31 last year, Wai Kai-ming, 37, conspired with Chak Tsan-wing, a pub operator, and Gary Lam, a suspected triad member, to pervert the course of justice.

They allegedly agreed to arrange for the commission of dangerous drug offences by people, and the arrest of these people by Police. As a result of the staged operations, Chak could falsely present himself as an informer assisting Police to get a reduced sentence in a criminal prosecution against him. Chak was at that time being prosecuted for allegedly possessing 'ice'.

Chak, 47, and Lam, 28, were earlier charged with a similar conspiracy offence for their roles in the case. Chak pleaded guilty and will be sentenced tomorrow. The court has issued a warrant for Lam's arrest after he failed to appear in court.
