Renewed appeal over police officers murder in North

 
Detectives in the North are renewing an appeal for information on the tenth anniversary of the murder of Constable Ronan Kerr.
The 25 year-old officer died after a bomb exploded under his car in Omagh on the 2nd of April, 2011.
It happened as he left his apartment in Highfield Close at a quarter to 4 that afternoon to go to work in Enniskillen.
The PSNI still believes there are witnesses in the community who may hold the key to vital evidence.
