In the North, officers investigating the murder of a Monaghan man have arrested a fourth person.
19-year-old Jason McGovern died after being assaulted twice at two separate venues in Omagh, Co. Tyrone on Sunday.
A 19-year-old man - who is from the Omagh area - was arrested by the PSNI this evening.
This brings to three the number of people in police custody in relation to the incident.
A 17-year-old boy was detained in Omagh earlier today, while an 18-year-old man who was arrested yesterday is still being detained.
A fourth man was released without charge.
