A mechanic who boasted about his criminal exploits in a bid to recruit a man into his gang of robbers caused his own downfall when the man turned out to be an undercover police officer. The robber also turned in one of his fellow gang members to police after he was arrested, the District Court heard yesterday. Ho Kwong-yat, 26, admitted one charge of robbery and one charge of incitement to robbery, for which he was jailed for three years and nine months. Restaurant worker Fan Wai-man, 20, was jailed for three years after pleading guilty to robbery. Judge Chua Fi-lan heard an undercover officer met Ho last August and during a tape-recorded conversation, Ho tried to persuade the officer to drive a car during a raid on a garment shop. Ho told the undercover officer that, together with his 'big brother', he had recently robbed a taxi driver and locked him in the boot. The officer agreed to drive the getaway car in the planned raid but delayed the robbery by saying he could not arrange a vehicle. Ho was arrested before the plan was executed. Ho admitted both offences to police and told them Fan had also participated in the robbery of the taxi driver on July 23, leading to his arrest. The court heard that Ho, Fan and his 'big brother' had taken the taxi to Lung Cheung Road, Cheung Sha Wan, where they robbed the driver and forced him into the boot of his vehicle. The 'big brother' was never caught. Judge Chua said the offences warranted five years' jail, but both received reduced terms because of their co-operation with police and guilty pleas.
