A 19-year-old, arrested by detectives investigating racist attacks on more than 100 Romanians in Belfast, has been released on bail pending further inquiries.
The suspect was questioned about the intimidation that forced the families to flee their homes last week and seek sanctuary in a church.
He had been taken into custody in south Belfast last night.
Up to 100 of the 114 eastern Europeans targeted have now decided to quit Northern Ireland altogether.
Already, 25 have flown home and another 75 are planning to go in the next few days.
Just 14 have decided to stay in Belfast.
A 21-year-old man appeared in court in Belfast yesterday charged with intimidating the Romanians.
On Monday, boys aged 15 and 16 appeared in court on charges linked to the attacks.
Two more teenagers, aged 16 and 17, who were being questioned were released last night pending further inquiries.
