The government has said that top officials of a Christian college set up to help students quit drugs have only themselves to blame for its imminent closure.

Directors of the Christian Zheng Sheng College announced on Friday that the school on Lantau Island would close on July 7. It comes after four members of staff were arrested in a conspiracy to defraud case.

Three former board members of the association are on the wanted list.

The association's new directors said police had frozen HK$4 million in the college's bank accounts, and the government owed HK$3.5 million in project fees.

In response to an RTHK enquiry, the government denied owing the cash-strapped college money and said it had provided emergency funding.

"In fact, as long as the two fugitive former directors of the Christian Zheng Sheng Association, Jacob Lam and Alman Chan, cooperate and complete the procedures to change bank account signatures, the problem can be solved," the spokesperson said.

The spokesperson added that officials are offering assistance to students affected by Zheng Sheng's closure, including helping to transfer five of them who are currently living in a drug rehabilitation under the college.

Speaking on a radio programme on Sunday, the college's supervisor Choi Hong-sheung criticised the new directors for being influenced by the two former directors.

Choi and three other board members resigned on Friday.
