Two men have been arrested on suspicion of selling electronic cigarettes in a joint operation between the police and the Department of Health.

Officers raided a mobile retail outlet in Mong Kok on Wednesday, and seized a batch of suspected alternative smoking products (ASP), including 94 boxes of suspected nicotine-containing e-cigarette cartridges and 74 smoking devices.

The suspects, aged 28 and 31, were arrested for the suspected illegal sale and possession of part one poisons as well as the suspected illegal sale of ASP.

They were still being detained by the police as of Thursday afternoon.

A spokesman for the Department of Health said they are committed to enforcing the new legislation that bans ASP which came into force late last month.
