A mother has been caught taking her two children - including one in a buggy - across a busy railway line in Essex.
She was caught on CCTV taking a shortcut over the line at Pitsea. Trains run regularly along the route from Southend-on-Sea into east London.
Police say hundreds of children and young adults - as many as 14 a day - risk their lives and those of rail passengers and staff every year by trespassing on railways.
Nationally, between April and June this year police recorded almost 2,400 incidents of trespass, of which almost 1,300 involved people aged 25 or younger.
The CCTV images have been released to highlight the dangers.
