A Portuguese serial killer dubbed the "Lisbon Ripper" is being hunted across Europe. He is being sought by police in four countries where he has killed, as well as in Portugal. The "Ripper" is believed to have killed at least seven women since 1992, three in Portugal and one each in Belgium, the Czech Republic, Denmark and The Netherlands. All his victims, the last of whom was murdered late last year, were young, drug-dependant prostitutes. The consistent pattern of the murders has convinced Portuguese police and Interpol that the killings were committed by the same man. Victims have been strangled, then disembowelled with a shard of glass. On no occasion has there been evidence of rape. He is believed to be white, aged between 35 and 40, tall, with a pathological hatred of women, and probably suffering from Aids. Police think that he may be a lorry driver whose work takes him across Europe.
