Police in Londonderry are continuing to question a 12-year-old boy and two 17-year-olds after officers were attacked with petrol bombs during a security alert.
Five petrol bombs were thrown after a suspicious device was found near a polling station in the Galliagh area.
The device close to St Paul’s Primary School was later declared an elaborate hoax.
Police have described the attack as “orchestrated disorder”.
