Responding to news of an arrest in the police investigation into the 2001 murder of Northern Ireland journalist Martin O'Hagan, Patrick Corrigan, Amnesty International’s Northern Ireland Director, said:

“This is potentially the most significant development since charges against four men were dropped in July 2010.

"The public execution of Martin O’Hagan was designed to send a clear message to journalists in Northern Ireland that they are not safe. 

“It is unacceptable that, in the twenty-four years since Martin O’Hagan was shot dead, no one has been held accountable.

“This failure has created an environment of impunity for those who continue to threaten journalists in Northern Ireland today.”
