Humberside Police are working to find a 13-year-old boy who was swimming in the sea off the South Promenade area of Hornsea on Tuesday evening. Police received reports of a concern for the boy’s safety at around 6pm and have since launched an “extensive search and rescue operation” to locate him. It comes after a 14-year-old boy drowned after going into the water in east London on Monday. Tuesday’s incident in East Yorkshire occurred less than 20 miles away from where 15-year-old Grace Keeling was swept out to sea in January.
