Police have investigated three allegations of rape linked to singles dating app Tinder.
Following a Freedom of Information request, the Birmingham Mail have also revealed that there have been a rising number of offences involving the gay dating app Grindr.
The force has dealt with the alleged Tinder sex attacks over the last five years, along with 14 other alleged serious offences.
Of the three rape investigations, one alleged victim could not be traced.
The other 14 crimes included four incidents of distributing an indecent image of a child, sexual assault, causing a female to engage in sexual activity and causing grievous bodily harm with intent.
The Freedom of Information figures show where Tinder or Grindr has been mentioned in the description of an allegation, although the apps may not have been used to commit the crime.
