CALGARY, Alta. – The Calgary Police Service (CPS) announced on April 15 that it was looking for information from the public about a man who had attacked a taxi driver last year. On Aug. 10, the driver picked up a male passenger and drove him across the city at about 12:30 in the morning, according to a CPS press release. After paying his fare, the passenger suddenly punched the cab driver in the face several times and began choking him. The attacker did not attempt to rob the taxi, but left the driver with facial injuries. The CPS did not state any reason for the attack, but added that the assailant had subsequently fled on foot and that the driver had tried to attract attention with the car horn. The release described the perpetrator as Caucasian with red hair, of medium build, about 1.7 metres in height and unshaven; at the time of the attack, the man reportedly wore a beige, long-sleeve shirt, jeans and a beige baseball cap. The CPS requested of anyone with information about the incident or identifying the attacker to call (403) 266-1234 or provide an anonymous tip through Crime Stoppers.
