Detectives investigating the murder of a teenage girl have been given an extra 36 hours to question a 30-year-old man arrested on Thursday.
Wendy McAteer's body was found near her old school
The body of 17-year-old Wendy McAteer was found at Blackburn Path in Limavady at about 2230 GMT on Wednesday. The path runs between two schools.
It is unclear how she was killed, but police have appealed "to witnesses to an assault".
A detective said she was last seen in a local bar on Wednesday afternoon.
Miss McAteer is believed to be a past-pupil of St Mary's High School, one of the schools near where her body was found.
Local priest Fr Michael Collins said it was alarming "that a 17-year-old girl could be killed in this way".

"It frightens us because it seems to be a part of culture nowadays that violence is simply seen as a solution to all the problems," he added.
East Londonderry MP Gregory Campbell said people in Limavady were "shocked" by the news.
"Any person that dies as a result of some form of incident is to be regretted, and I'm sure the sympathies of everyone will go out to the family," he said.
