A woman was raped in a graveyard by a man she met on a night out, police have said.
She was attacked in the grounds of St Laurence Church, in Reading town centre, between 01:00 and 02:00 GMT.
The victim, in her 30s, flagged down a police car to report the offence at about 03:00 GMT, Thames Valley Police said.
It described the suspect as a white man with "bushy eyebrows" and "dark coloured eyes".
Det Con Connor Hatton appealed to "anybody who believes they witnessed anything unusual or suspicious" to contact police.
