A 24-year-old man was charged last night in connection with the murder of Belfast teenager Megan McAlorum.
He was charged with withholding information about the murder and is due to appear at before Lisburn magistrates this morning, police said.
A woman remains in custody being questioned also on suspicion of withholding information.
A 16-year-old youth appeared in court yesterday charged with Ms McAlorum's murder. He denied the charge.
Ms McAlorum, 16, disappeared after leaving the Hunting Lodge pub in west Belfast's Stewartstown Road at around midnight on Easter Sunday.
Her semi-naked body was found the following day in an isolated forested area outside Dunmurry around a mile from her home in west Belfast's Lenadoon estate.
She had suffered extensive head injuries.
Police tonight staged a series of reconstructions a week on from her disappearance.
The were also spending the night stopping traffic and handing out posters on the Glenside Road, close to the wooded area where her body was found.
Detectives were also speaking to people in two other areas where they believe Megan might have been in the last hours of her life.
They particularly want to trace a taxi driver who was seen in a silver Ford Mondeo on the Shaw's Road in west Belfast between 2 a.m. and 4 a.m. last Monday.
