New arrest in McGuigan murder
A 46-year-old man has been arrested by police investigating the murder of senior republican Kevin McGuigan.
The man was arrested today in Antrim.
Detective Chief Inspector John McVea said: "The suspect is assisting officers at the Serious Crime Suite at Antrim Police Station."
A 41 year old man arrested on Wednesday, September 2, remains in custody.
Mr McGuigan was gunned down in front of his east Belfast home in the Short Strand last month.
It is believed that the killing was in retaliation for the murder of Gerard 'Jock' Davison in May in the nearby Markets area of east Belfast.
The killings have led to the current political stalemate in Northern Ireland, with the Ulster Unionist Party quitting the Stormont Executive to form an opposition.
After the hit on McGuigan, the Chief Constable of the PSNI, George Hamilton, said he believed that members of the Provisional IRA were involved in the murder.
