Hong Kong police have arrested three people in connection with a knife attack on three customs officers during an anti-drug operation, including the assailant’s mother, who allegedly provided misleading information to the force, the Post has learned.
Two men, arrested in Mong Kok at 12.45am and in Kowloon City at 3am on Friday, were believed to have aided in the escape of the wanted attacker.
A 66-year-old woman, identified as the attacker’s mother, was arrested at 2.45pm on Friday in Wong Tai Sin on suspicion of misleading police officers, a source said.
According to the source, eight customs officers who mounted an operation on Thursday stopped a wanted man and brought him to a flat in To Kwa Wan for investigation, during which he injured three of them with a 30cm kitchen knife.

Police soon arrived at the scene to back up customs, with paramedics treating the injured officers, aged 29 to 42, who sustained knife wounds between 4cm and 10cm long on their knees, forearms and heels, the insider added.
The wanted man, aged 38 and about 1.75 to 1.8 metres tall, was nowhere to be seen when police broke into the flat after customs officers had evacuated and locked him inside.
He was believed to have escaped through the kitchen to a back staircase, with closed-circuit television footage showing him headed towards Lok Shan Road.
Police later found a black Toyota registered to him at Grandview Garden, a residential building, as well as the knife used, at 47 Cheung Ning Street.
Police seized suspected replica firearms and narcotics from the flat. Investigations are continuing. -- SOUTH CHINA MORNING POST
