Four people have been arrested in connection with the murder of Geoff Kerr who was gunned down on his doorstep.
Mr Kerr, whose funeral was held this afternoon, was shot in the chest after opening the front door of his home in Templepatrick on Monday.
The 60 year-old father-of-four, whose wife and one of their sons were in the house at the time, died instantly.
The PSNI said three men and a women have been detained and are being held for questioning.
Two men were arrested in the Glengormley area, and a third picked up in the Antrim area. The female suspect was arrested on suspicion of aiding and abetting.
They have all been taken to Antrim Serious Crime Suite for questioning, a PSNI spokeswoman said.
A number of searches have also been carried out in the Greater Belfast area, she added.
Hundreds of mourners, who gathered at Templepatrick Presbyterian Church this afternoon to pay their last respects to Mr Kerr, were told he was a “special person” who enjoyed life to the full.
Rev Richard Kerr, who led the service, said the financial adviser was very much a family man who was devoted to his wife Sally and their four children.
He said: “Geoff Kerr was a special person; and I don’t say that lightly. To have met him was a privilege, an experience, he drew you in with his chat and charm.
“To know him as a husband, father, was to know a man who loved you dearly, would have done anything for you.”
He added: “He was a family man, someone who was devoted to each one of you.
“Whenever I spent time with him, he talked about his boys, and his pride in you and love for you was evident.
“He was so central to your lives; he lived for you. It was him that you relied on. His strength and love were so much part of your lives. Whenever there was a challenge, Geoff always had a solution.”
