Mr Moffatt was attacked in the Railway Road Circular Road area of the town as he walked home after buying a newspaper shortly before 8am on 26 January 2001.
The 73-year-old died in hospital two months later.
No one has ever been convicted of killing Mr Moffatt and his son Barry said the death was a blow to the local community.
"It was very hard to believe that something like that could happen right on your very own doorstep, especially in Coleraine."
At the weekend, a 42-year-old man was arrested in England.
He was detained in the Stockport area of England by detectives from Greater Manchester Police and the PSNI and has been taken to Antrim police station where he is being questioned in connection with the pensioner's murder.
"It came as a shock to us even after 10 years but it's come as welcome news but as we know there's a long way to go," added Barry.
For the Moffatt family, they hope a conviction would offer them some closure.
