Falling number of child arrests
Police patrolling Britain's railways arrest on average 40 children a week, a safer communities charity has found.
British Transport Police made 2,090 arrests of boys and girls aged 17 and younger during 2011 - a 12% fall from 2009, when 2,374 arrests were recorded, figures obtained by the Howard League for Penal Reform showed.
The charity said the fall in the number of girls' arrests is "particularly significant" - down by 38% from 341 in 2009 to 210 in 2011. Over the same period, the number of arrests of boys fell from 2,033 to 1,880.
Frances Crook, chief executive of the Howard League for Penal Reform, said: "The British Transport Police have a hugely important role, working to save lives and promote public safety. When children play near railways, it is extremely dangerous.
"The police should see their role in that context: not criminalising children for being naughty, but showing them how that behaviour is putting their life at risk. It's about education, not about punishment.
"The significant fall in the number of children entering the justice system is good news for everyone striving to reduce crime and saves the taxpayer untold millions. With government cuts leaving many forces stretched to the limit, further reducing the number of children arrested would mean more police time could be freed up to deal with serious crimes."
British Transport Police arrested 29 primary school-age boys between 2008 and 2011, six 10-year-olds and 23 11-year-olds.
A nine-year-old girl was arrested in 2008, even though the age of criminal responsibility in England and Wales is 10, the charity revealed.
In total, more than one million child arrests have been made in England and Wales since 2008, it added.
