Britain's most senior police officer has saddled up to join mounted officers patrolling a Premier League derby match.

Metropolitan Police Commissioner Sir Bernard Hogan-Howe kept an eye on Chelsea and Arsenal fans while perched on police horse Oliver.

The top of the table clash attracted 41,490 fans to Stamford Bridge.

A spokesman said Sir Bernard has attended patrols "quite a lot" since being appointed in September 2011.

He is due to retire next month, after five years in the role.
