No further police action is to be taken against four men from London who were arrested in connection with a shooting at a club in Suffolk.
A fifth man, a 23-year-old, who was arrested after five people were injured at the Caribbean Club, Woodbridge Road, Ipswich, remains on police bail.
A man suffered a gunshot wound and four others were hurt at the club last December.
Suffolk Police want to talk to anyone who was there at the time.
