Detectives investigating a road tragedy which killed an 80-year-old historian have arrested a man.

The 66-year-old, from Shipley, was detained yesterday in connection with the death of retired teacher Alan Naylor, but has been released on police bail pending further inquiries.

Mr Naylor died in Dewsbury District Hospital four days after he was in an accident with a car at 9.45pm a week last Wednesday.

The accident happened as pedestrian Mr Naylor was crossing New North Road just 20 yards from the Six Lane Ends junction in Heckmondwike.

Mr Naylor's brother, David, travelled from his home in Ireland to make an appeal for information in a press conference at Dewsbury police station on Wednesday.

He said: "Alan has left a huge gap in our lives and we miss him greatly. It's been a huge shock."

Mr Naylor had a number of local history articles published in magazines along with a book of historical photographs featuring Birstall. Unmarried, he had taught in Birstall and Norristhorpe.
