Crews were back in Oxford to film the fourth series of Endeavour last weekend, with snapper Nasir Hamid sharing exclusive images taken while filming at Headington Cemetery.

On his blog, simplyoxford.com, he wrote: "The Endeavour cast and crew were in town last weekend to work on episode three of the fourth series and I was fortunate enough to do some behind the scenes photography of them at work.

"Usually I don’t post my pictures so soon after making them but I wanted to share these so that the Endeavour team could have a little peek at what ended up being quite a tense finish to the shoot in Headington Cemetery here in Oxford as the sun was rapidly heading towards the horizon and the light was fading."

The photographer added that he tried to be "invisible" while on set and added: "A huge thanks to all of the cast and crew for allowing me to photograph one of my favourite things – them at work. I just wish I could do more of it."

Cast members were also spotted in green spaces around Oxford and near the Bridge of Sighs on Sunday.
