A drone with a thermal imaging camera had to be used to trace a teenage girl who called 999 from an unknown location to report she was with a man who had allegedly raped her.
Lincolnshire Police said the missing “high risk” 16-year-old called in the early hours of Saturday from the Brown’s Road area of Boston.
She could not give her location, but described still being with her attacker in an old industrial complex surrounded by a high fence.
The force said the thermal drone was used to find the girl and guide officers to her within minutes.
A man in his 30s was arrested and remains in custody, officers said.
