The Batman rapist is an unidentified English serial sex offender who committed at least seventeen sexual assaults on women in the city of Bath, Somerset, between 1991 and 2000.[1][2] He is the subject of Britain's longest–running serial rape investigation, codenamed Operation Eagle, and has now eluded capture for more than thirty years.[2][3] Detective Inspector Paul James of Avon and Somerset Constabulary, leading the operation, said it is "one of the most complicated and protracted investigations" that the force has ever undertaken.[4] In January 2001, the Forensic Science Service used the Low copy number (LCN) DNA profiling technique to isolate the rapist's DNA "fingerprint".[5] They then began the process of taking swabs for comparison from all the men, believed to be around 2,000 individuals, whose names had come up during the course of the investigation.[4][6]
The perpetrator was nicknamed after leaving a baseball cap bearing a logo from the Batman film series at the scene of one attack.[7] Police believe that there are more victims who have never come forward.[8] The independent crime-fighting charity Crimestoppers UK have offered a £10,000 reward for information leading to his capture.[3] The perpetrator has also been referred to in the news media as the "Riddler".[9][10][11] The case was highlighted on the BBC's Crimewatch on 25 January 2000, including an appeal from Avon and Somerset Constabulary for information from the public.[12] As a result of the appeal, six previously unknown victims came forward.[2][13] Callers also gave the names of four potential suspects, including the son of a British diplomat, and "dozens of calls were received from prostitutes and partners of people with similar sexual habits".[9][14]
