Night Stalker Delroy Grant has been convicted of being one of the most prolific and depraved sex attackers in British history. The 53-year-old rapist was found guilty of preying on the elderly in a campaign of perverted terror lasting 17 years. Former minicab driver Grant was responsible for some of the most "awful and disturbing crimes" ever investigated at Scotland Yard, senior detectives said. A jury at Woolwich Crown Court convicted him of claiming at least 18 victims - but it is feared the total may be more than 500.
