Police release four held over Portrush death
Police in the North have released four people they were questioning in connection with the death of a 14-year-old boy in the North last week.
Ryan Quinn died after being hit by a train on Friday night near Portrush in Antrim.
The police are investigating reports that he was being chased just before he died.
Three men and a 15-year-old boy were arrested by the PSNI over the weekend, but they have since been released without charge.
