A 60-year-old man drowned after trying to rescue two children in distress in the sea near Skegness.
Shortly after 4pm on Sunday, the man entered the water near the Promenade in Ingoldmells, Lincolnshire, police said.
Emergency services were called, but the man got into difficulty and died at the scene.
An air ambulance, the coastguard and the Royal National Lifeboat Institution had been called to the scene.
In a statement, Lincolnshire Police said: ‘Our thoughts are with the man’s family and loved ones at this very sad time.”
No further information has been released about the children involved.
The accident came just days after a four-year-old British boy drowned in a hotel pool in Tenerife.
The youngster was reportedly pulled from the water by a lifeguard in the resort town of San Miguel de Abona.
He had gone into cardiac arrest and was unresponsive, according to Spanish outlet Telecinco.
