ATLANTIC CITY, N.J. — Authorities say a Pennsylvania man died while rescuing his son who was struggling in rip currents while swimming in the ocean off Atlantic City, N.J.

Emergency responders went to the beach around 9:30 a.m. Monday on a report of a child drowning.

Before they arrived, 58-year-old Thanh Bui, of Reading, had entered the water to help his 11-year-old son, who eventually made it to shore.

But Bui began struggling, and a former police officer who happened to be at the beach entered the water and tried to pull him.

Emergency responders soon brought the two men ashore, but Bui was unresponsive and was soon pronounced dead at a hospital. The former police officer wasn’t injured.
