A group of hikers rolled videotape and took photographs as a bear entered their camp at High Point State Park and bit a sleeping counselor, New Jersey wildlife authorities said yesterday as they continued to investigate the incident.

The 19-year-old Pennsylvania counselor, camping with about five other hikers along the Appalachian Trail, suffered raised welts on his left thigh when the 142-pound female bear bit into his sleeping bag around 6:30 a.m. on July 13, authorities said.

Martin McHugh, director of the state Division of Fish and Wildlife, said yesterday that wildlife officials were disturbed by the behavior of the hikers, the boldness of the bear and the fact that the incident was not reported to his office until July 21. It was not until last week that a trap was set at the campsite for the bear, which was captured and killed Friday.

"As soon as the bear entered the camp, the counselors or those in charge should have taken measures to scare it off and not just take photographs and videotape it," said Larry Herrighty, chief of the division's Bureau of Wildlife Management.
