Do you recognise this man in the picture.
Police want to speak to this man following an arson attack on Farebrother Street that threatened the lives of a mum and her three children.
Humberside Police have released CCTV footage following the incident in the early hours of Wednesday April 10.
A mum and her three children were only saved from the blaze in their front doorway after they were alerted to it by their two-year-old Dogue de Bordeaux, Kaiser.
The man is of stocky build, with brown hair and a small moustache on his upper lip, and is pictured wearing a navy blue Hugo Boss jumper, with red and white stripes on the sleeves, and a red hat.
A Humberside Police spokesperson said: “We are appealing for help to ID the man shown in these CCTV images.
“We want to speak to him in connection with a fire at a house on Farebrother Street in Grimsby at around 3am on Wednesday 10 April.
“Do you recognise him? If you know who he is please call us on the non-emergency number 101 quoting reference 16/46122/19.”
