DNA extracted from a pair of shoes left behind in a cake shop led to the arrest of a barefoot robber who bashed a shop assistant with a hammer, a court heard yesterday. Chan Wing-hong, 46, was jailed for eight years for the attempted robbery at Arome Bakery in Nathan Road, near Yau Ma Tei, on September 29 last year. He pleaded guilty in the Court of First Instance to a charge of assault with intent to rob. Security camera footage of the attack was played in court yesterday. It showed Chan run into the shop at about 7.40am, take out a hammer and strike Chan Hau-man twice on the head. The video showed the defendant flee after Ms Chan shouted for help. His white fabric shoes came off as he escaped. Ms Chan's wounds required five stitches. Government lawyer Jonathan Man Tak-ho said that police arrested Chan three hours later near the junction of Shanghai Street and Bute Street. He was barefoot. DNA later extracted from the white shoes matched Chan's. The prosecution revealed Chan had 14 convictions involving robbery, theft, assault, escape from prison, blackmail, managing vice establishments and claiming to be a triad member. Sentencing him, Deputy Judge Derek Pang Wai-cheong said it was only by luck that the victim was not seriously hurt. He adopted a starting point of nine years' jail and reduced it by just one year, saying the defendant had tried to reverse his guilty plea and thus had showed no remorse.
