Mackenzie Crook

Actor Mackenzie Crook has appealed for help in finding his sister-in-law, who has Gone Missing in West Sussex .

The Star , known for his roles in Pirates of The Caribbean and The Office , is part of a Search Party looking for Laurel Aldridge.

The 62-year-old, who is currently undergoing chemotherapy, was last seen in Walberton, near Arundel, on Tuesday, Sussex Police said.

Crook, 51, is urging locals to check in their gardens, bins and garages.

" It's incredibly difficult. She is in quite a vulnerable position at The Moment , " he told.

" She missed a chemotherapy session on Tuesday, so we're really worried about her.

" There were reported possible sightings of her as Far North as Bignor Hill , but we've discounted those and we think she is very much in The Local Walberton area. "

Crook, who grew up in Kent, added that she is a " wonderful mother" and " usually very happy. "

Police say they are concerned for Ms Aldridge's welfare, and are urging anyone who sees her to call 999.
