The PSNI is appealing for information following a petrol bomb attack in Derry, in which an 11-year-old boy sustained serious burns.
Kevin Grint was stuck by the petrol bomb in a play park in the Creggan area of the city.
There was no rioting or disturbances in the area, but apparently without warning a petrol bomb was thrown at the child.
When the device exploded, the child was engulfed in flames and suffered extensive burns to his back.
His mother, Donna, who was at home a few hundred metres away heard her son screaming and rushed to help.
The child was later transferred to the specialist burns unit at the Royal Victoria Hospital in Belfast where his condition is described as stable.
Police suspect that two other boys, aged about 12 or 13, may have been involved in the incident.
They have appealed for anyone who knows who they are or who has any information to come forward.
