SAN JUAN, Puerto Rico -

The Coast Guard and Puerto Rico police rescued two fishermen Thursday night, and two others are still being sought after their boat capsized north of Vega Baja, Puerto Rico.

Coast Guard officials said the four fishermen reportedly departed on a fishing trip Thursday morning from Cerro Gordo Beach in Vega Baja when their boat capsized at noon.

All four men were reportedly wearing lifejackets when they went into the water, officials said.

Coast Guard watchstanders in Sector San Juan received a report Thursday night from Ricardo Román that a resident in the area reported seeing from shore a red flare out at sea.

After arriving at the scene, a crew on the Coast Guard helicopter found the first fisherman after initially sighting a beam of light from a flashlight that was coming from the water, authorities said.

Officials said shortly thereafter the crew found the second fisherman two nautical miles south from the first fisherman's position.

The two fishermen were transferred from the Puerto Rico police marine unit to a good Samaritan's boat that helped in transporting the rescued men to Cerro Gordo Beach in Vega Alta, where officials said they were received by awaiting emergency medical services personnel.

The search continues for the other two fishermen who were also reportedly on board the boat.
