Two men have been arrested after a 14-year-old girl was raped twice on the same night.
Detectives said the teenager was first assaulted in a secluded part of Birmingham's Witton railway station, near the Aston Villa football ground, between 8pm on Tuesday and 2am the following morning.
Shortly after that attack, the girl walked out of the station and flagged down a passing vehicle to ask for help, but was raped a second time after getting into the car with another man.
Police said the arrests of two men, aged 35 and 27, on suspicion of rape on Saturday morning both relate to the first attack. The pair are in police custody.
Detectives are still searching for another man, who is described as about 5ft 6in, thick set and with large biceps, in connection with the second rape.
Detective Chief Inspector Tony Fitzpatrick, from British Transport Police, said: "Our investigation into the second incident in the vehicle continues at a pace.
"The young victim was raped for a second time in a vehicle close to Witton station at approximately 2am.
"I am still looking to hear from anyone who lives locally to Witton and saw a young girl walking by herself during the early hours of Wednesday morning.
"If you saw any vehicle or any person acting suspiciously then please get in touch as soon as possible."
