Jason McGovern death: Fourth arrest in police investigation
Police investigating the murder of County Monaghan teenager Jason McGovern in Omagh have arrested a fourth person.
It is believed Jason McGovern, 19, of Tydavnet, was punched at a pub on John Street on Sunday. He was hit a short time later at Cunningham Terrace car park and later died.
A 19-year-old man from the Omagh area was arrested on Thursday evening. Hours earlier, police detained a 17-year-old boy from town.
Two others were arrested on Wednesday.
The men, aged 18 and 21, were also detained in Omagh and the teenager is still being questioned.
The 21-year-old has since been released on bail.
After being attacked, Mr McGovern made his way to a friend's house in Mullan village near Emyvale in County Monaghan where he was found dead on Monday.
The investigation will be led by the Police Service of Northern Ireland (PSNI) and supported by the Garda.
A post mortem examination showed the teenager's death had been due to a head injury he suffered during the initial assault.
