Emergency services were searching the Thames on Monday for a teenage boy who was seen getting into difficulty in the water, hours after the body of a woman was recovered from the river two miles away. Thames Valley police said on Twitter that officers were at the river between Bourne End, Buckinghamshire, and Cookham, Berkshire on Monday, following a report of a fear-for-welfare incident. The force received a report at 3pm that a teenage boy had entered the water, got into difficulty and was not seen leaving the water, prompting a search by police and the fire service. Officers said there would be a police presence in the area while the search takes place. Officers were called to Boulters Lock in the Thames in Maidenhead, Berkshire, earlier on Monday, after a report of a woman’s body in the river at 7.15am. Thames Valley police said the death was being treated as unexplained and that formal identification had yet to take place. Officers were working to establish the circumstances surrounding the death and to identify a next of kin. Boulters Lock and Cookham Lock are both closed and police are asking that members of the public avoid the area. In Hampshire, a two-year-old boy was in a critical condition in hospital after being pulled from Swanwick Lake, a nature reserve near Fareham, on Sunday. Hampshire constabulary have arrested an 18-year-old man from Southampton, who officers said is known to the boy, in connection with the incident.
