An 80-year-old pedestrian suffered head injuries when she was hit by a cyclist who had lost control of her bicycle in an underpass in Ma On Shan yesterday. The cyclist, 57, was slightly hurt. The accident happened less than 24 hours before police launch a nine-day campaign to promote safe cycling. According to the latest police figures, in the first three months of the year three cyclists were killed and 289 injured in 333 accidents. In the same period of last year, 321 cyclists were hurt in 351 accidents but there were no fatalities. Yesterday's accident occurred when the cyclist was riding downhill in the underpass outside Villa Athena at the junction of On Chiu Street and Sai Sha Road in Ma On Shan at 7.50am. Both women were taken to Prince of Wales Hospital, where the 80-year-old was in stable condition. The cyclist was discharged from hospital after treatment. During the nine-day safety campaign, police will distribute leaflets in areas popular with cyclists, including bike tracks, railway stations and shops that use bicycles to deliver takeaway food. Police said offenders would be given verbal warnings in the first four days of the campaign and stringent action would be taken against offenders from April 25 to 29. Common offences include carrying a passenger, carrying animals or articles that obstruct the cyclist's view, riding on footpaths and riding without lights. A police spokesman said: 'Cyclists are subject to the Road Traffic Ordinance once they are on the road. They should also be conscious of other road users.'
