A young couple begged a gang of robbers not to take their eternity rings minutes before being beaten to death with a pick-axe handle, a court heard. The sweethearts wore the rings as symbols of their love, and were desperate to keep them even when tied up and blindfolded. Prosecutors claim Yung Tze-lung, 21, and his girlfriend, 16-year-old Chan Chin-yee, were repeatedly hit on the head in an abandoned hut in Lantau on September 7, 1995. However, the High Court yesterday heard the heartfelt request momentarily touched the hearts of the brutal gang members, who let the lovers keep the tokens. Police found the rings still on the fingers of the battered and bloody bodies, recovered five months later. Gang member Cheung Moon-keung, a 30-year-old jeweller who has pleaded not guilty to murder and preventing proper burial of the victims, described the incident. He has admitted robbery. Cheung is accused of carrying out the killings with Lo Yau-fuk, 28, and Lam Chung, neither of whom is on trial. Cheung said: 'The rings clearly meant great significance to the boy and girl. I told Lo not to take them.' Wallets and other belongings were stolen. Cheung told the court Lo then told him to shine a torch on the young man - whose eyes had been covered with canvas tape, and feet and arms bound with metal wire. Lo ordered the light off. Cheung said he saw Lo silhouetted in the moonlight as he hit Yung over the head four or five times with the pick handle. He was then told to turn the light on and to give the torch to Lam who was backing away in fear. Lo inspected his handiwork before he picked up the handle again and ordered the light off, Cheung said. Then he attacked the girl, who had been lying tied-up in a corner of the stone hut. When the light was turned on again, Cheung said he saw a pool of blood on the floor and was terrified. The victims' skulls had been crushed. Cheung claims he agreed to participate in the robbery but had no idea the couple were to be killed. He claims Lo was behind the murders. Prosecutors allege Lo lured the couple to the island and arranged for his accomplices to meet him at the hut. The trial continues today before Mr Justice Mohammed Saied.
