A 33-year-old serving police woman has been charged with a number of offences in connection with the murder of James McDonagh last month.
Mr McDonagh, from Castledawson, died in the Royal Victoria Hospital on Monday, January 11.
The 28-year-old sustained severe head injuries after being assaulted outside the Elk Inn bar and nightclub complex in Toomebridge.
The police woman was arrested in Banbrige last month for questioning and was released on police bail pending further inquiries.
She now faces two counts of perverting the course of justice and a charge of withholding information.
The officer will appear at Magherafelt Magistrates Court later this month for a first remand hearing.
Detective Chief Inspector Eamonn Corrigan said tonight: “The woman was arrested and questioned last month and returned to answer her bail today.
“As a result of our inquiries and following consultation with the Public Prosecution Service, she has been charged to appear at Magherafelt Magistrates’ Court on February 17.”
A 24-year-old man has been already been charged with Mr McDonagh’s murder.
Finbar McCoy, from Loughbeg Road in Toomebridge, appeared in court last month.
He denies murdering Mr McDonagh but admitted assaulting him.
The 24-year-old was remanded in custody.
