Reynhard "Rey" Tambos Maruli Tua Sinaga (born 19 February 1983) is an Indonesian serial rapist who was convicted of 159 sex offences, including 136 rapes of young men, committed in Manchester, England, between 2015 and 2017, where he was living as a student. Sinaga was found guilty of drugging and sexually assaulting 48 men during this period, 44 of whom he raped, some repeatedly, although police believe he was offending for years beforehand. Sinaga was prosecuted in four trials between 2018 and 2020 and was given concurrent life sentences with a minimum term of 30 years, raised to 40 years in December 2020 by the Court of Appeal. The Crown Prosecution Service described Sinaga as being the most prolific rapist in British legal history. Sinaga is believed by police to have raped or assaulted at least 206 men since 2015, which includes the two years before his arrival in the UK. In Manchester, he waited for potential victims outside nightclubs, pubs and similar venues in the early hours. He then offered his victims a stay at his flat, subsequently drugging and raping them. After some of the assaults, Sinaga boasted about his actions on WhatsApp.
