A portion of Huntington Beach was closed Friday after a surfer reported an aggressive encounter with a great white shark off the coast.
The closure began at Beach Boulevard and extended along the coastline about 1 mile in each direction, according to Huntington Beach Watch Commander Lt. Claude Panis.
The shark sighting was first reported about 8:45 a.m. by a surfer who is well known to many of the local lifeguards, Panis said.
"He was sitting on his board, and he noticed that the water around him started boiling, and right after he noticed that, he felt a sharp bump underneath his board, and it kind of got his attention," Panis said.
"He looked and he saw a shark that he described as being black in color and it was swimming south after it bumped him, swimming away from him," Panis said.
The surfer said he was about 30 yards from the shore when the shark -- estimated to be between 5 and 8 feet long -- bumped into him, Panis said.
"The 'bump' meets the criteria for aggressive behavior, and with that our protocols call for a precautionary closure of the water for 1 mile in both directions," according to an alert from the city.
The closure was expected to last through 8 a.m. Saturday pending any additional sightings.
