A 37-year-old man suspected of murdering his 32-year-old ex-wife in September last year is led by police yesterday through a recreation of the alleged crime in Tsuen Wan.

The body of his ex-wife was found lying on a bed in her flat on Shek Yam Road on September 29, police said. A post-mortem examination revealed she had been strangled.

The man had been living on the mainland and was arrested at the Lowu border checkpoint when he returned to Hong Kong at about 4.45pm on Wednesday this week.
