The Director of Public Prosecutions will cancel the Marine Department summons against Diaoyu Islands activist Lo Hom-chau, after ruling it is not in the public interest to prosecute him.

Mr Lo was notified of the decision today, and reminded to comply with the law, particularly the Merchant Shipping (Local Vessels) Ordinance.

A similar warning letter was also issued to fellow activist Yang Kuang.

On February 14 the Marine Department issued a summons against Mr Lo for leaving Hong Kong on August 12 last year, and disregarding the condition of a vessel and directions to stop it.

The summons was cancelled by Eastern Magistracy on February 27.

The department said, while the right to demonstrate and freedom of expression are protected by the law, the public must act in accordance with the law, including the legal requirements for the maintenance and use of vessels.
