A man has been arrested in connection with the murder of Dean Johnson in Dublin last month.

The 21 year old was shot several times - as he walked home from a night out with friends in Neilstown in Clondalkin on August the 24th.

This afternoon, a 27 year old man was arrested in Dublin's south inner city - for questioning in connection with the murder.

He's being held at Ronanstown Garda Station in Clondalkin.
