Met police officers used tasers on two 85-year-olds and a number of young teenagers, it has emerged. 

Figures released under the Freedom of Information Act show officers used the weapon on 11 people over the age of 60 in the 12 months up to April 2014 and 13 children aged 13 or 14 during the same period. 

Police used tasers in 4,105 incidents and fired them on 503 occasions.  

Conservative leader on the Greater London Authority, Andrew Boff, requested the information. 

He called for body-worn cameras to be activated as soon as tasers are taken from their holsters. 

He said: "Tasers are an important tool in public safety. 

"Wielded by a trained officer in an incident, they can help reduce harm to bystanders, the police, and even the person being fired on in an incident. 

"Without context, the use of a taser is questionable on elderly people or kids as young as 14, which is why the Met should invest in technologies that would remove any grey areas. 

"Body-worn cameras triggered by the use of the taser would capture the events leading to a needed intervention. 

"They have been shown to increase accountability whilst reducing complaints, protecting both police officers and the most vulnerable in society." 

The Metropolitan Police have been asked to comment.
