Police have only just released a CCTV video of a man they want to speak to about a cash machine arson that happened 18 weeks ago.
Thousands of pounds worth of damage was caused after the cash machine in School Mead, Abbots Langley, was set on fire at some time between 4pm and 4.50pm. The man who police think did it then headed off towards Hazelwood Lane.
