An appeal has been launched to trace a motorcyclist following a series of petrol thefts.

Police have released images of a motorcyclist they would like to speak to following the spate of petrol thefts across Hertfordshire, including Borehamwood and Potters Bar.

The crimes occurred at several petrol stations across the county between September 2012 and June this year.

All the thefts involved either a black Honda CBR Fireblade or an orange CBR Fireblade bike, which are believed to be ridden by the same person.

A total of 13 thefts are currently being investigated. They were committed in Borehamwood, Hitchin, Hinxworth, Bishop’s Stortford, Northwood, St Albans, Hertford and South Mimms.

Investigating officer Sgt Stephen Oliphant said: “We would like to trace the rider pictured as they may have information which could assist with our investigation. I appreciate this is difficult as their face is covered but the bikes are quite distinctive.

"If anyone knows who this person is, please get in contact with me. I would also like to hear from anyone who has information about the thefts.”

Anyone who knows the person pictured, or who has information about the thefts, is asked to contact PS Oliphant on the Hertfordshire Constabulary non-emergency number 101.
