Police fear two women who woke up with injuries after a night out with no memory of how they got them could have been spiked.
Greater Manchester Police are appealing for information after the incident in the early hours of Sunday morning.
The force say two women left a bar in Monton, Eccles, Greater Manchester and got into a silver people carrier.
The next memory they have is being at one of the victim’s home addresses, both women with multiple injuries. Neither can recall how they received them, the Manchester Evening News reports.
Enquiries have suggested that both the victims travelled in the taxi only a few hundred meters before exiting and were then subsequently picked up in Monton by a couple in a black Mercedes.

Greater Manchester Police said in a statement: "We would like to appeal for the following people and information:
"The taxi driver of the silver people carrier who collected and dropped off the victims on Monton Road.
"The driver and passenger of the black Mercedes who collected the two victims."
