Two men have been arrested by Gardai investigating the murder of David Byrne in Dublin in February.

The 33-year-old died after being shot a number of times at a boxing weigh-in at the Regency Hotel in Drumcondra.

One man was arrested yesterday evening while the second man was detained this morning.

Both men - are in their 50's - and are being held at Clontarf and Ballymun Garda Stations.

It brings to 7 the number of people arrested in relation to the murder investigation.

The shooting sparked a raft of revenge killings, culminating in the murder of Gareth Hutch last Tuesday.

A woman's been remanded in custody this morning, for allegedly withholding information about Mr Hutch's death.
