John Haase (born 1948) is an English gangster, drug dealer and associate of Curtis Warren. Haase and his nephew Paul Bennett are career criminals with convictions for bank robbery and drug smuggling. In 1996, Haase and Bennett were given a Royal Pardon 11 months into 18-year prison sentences for heroin smuggling, having provided information leading to the seizure of firearms. The Home Secretary, Michael Howard, was criticized for the decision, and in 2008 Haase and Bennett were convicted of having set up the weapons finds to earn them their release, and sentenced to 20 and 22 years in prison respectively.
