A SECOND person has been arrested relating to the death of a 15-year-old girl on Saturday, May 11.

Leah Heyes from Applegarth, Northallerton died in hospital after collapsing in a car park on Saturday evening.

It is believed that Leah had taken the drug MDMA, which is also known as ecstasy, prior to collapsing. 

She later died at the James Cook University Hospital in Middlesbrough, where it is understood a post mortem examination is being carried out.

Over the weekend, police said a 17-year-old had been arrested in connection with her death.

A second arrest of an 18-year-old man was made on Monday night, although police said both have been released pending further investigation.
