A 45-year-old man arrested in connection with the murder of Simon Tang has been released unconditionally.
He had been detained in north Belfast earlier on Tuesday.
Mr Tang, a father of two, was killed after a robbery at his Chinese takeaway in Carrickfergus in 1996.
Five people - three men and two women - have been charged with offences linked to the murder of the 28-year-old in the past few months.
