Cumbria Police are appealing for witnesses in relation to the death of a Workington man in the river Eden over the Easter weekend near Lazonby.

Officers are asking for anyone who may have witnessed a number of men in boats near Lazonby at around 3:20pm that day to get in touch.
Anyone with information is encouraged to contact PC 2221 Brownrigg on 101, referring to incident 152 of April 3.
