A 19-year-old man has been arrested on suspicion of murdering a schoolgirl who was stabbed to death as she walked home along an unlit riverside footpath.
The body of part-time Laura Ashley shop assistant Asha Muneer, 18, was discovered lying next to the River Kennet in Reading, Berkshire, by a jogger on Monday night.
The man was arrested shortly after 10pm on Tuesday at an address in Reading, Thames Valley Police said.
He added: "He was taken to Loddon Valley police station and will be questioned there in the morning."
Relatives at Miss Muneer's home in the Whitley area of Reading were too distraught to speak about her death.
A post-mortem examination carried out at a local hospital revealed the teenager, a pupil at Highdown School in Caversham, Reading, had died of multiple stab wounds.
Miss Muneer was found on the footpath, near the Madejski football stadium, at 8.30pm on Monday with her handbag lying nearby.
She is thought to have left work at Laura Ashley, on the Brunel Retail Park, more than two hours earlier, when it closed at 6pm. No ambulance was called as it was already too late to save the teenager.
A spokeswoman for Laura Ashley said the death was "shocking" and that the teenager's friends at the store, on the outskirts of Reading, were devastated.
The footpath, which passes under the A33 dual carriageway, is popular with fishermen, cyclists, joggers and dog walkers during daylight hours.
