Fighter jets intercepted a small private aircraft near Camp David on Sunday while President Obama was there, the third time in two days such an incident occurred. It was also the fifth interception in a month near the presidential retreat in Maryland.

There was no immediate indication of any link among the incidents.

In the latest case, two F-15E fighters sent by the North American Aerospace Defense Command intercepted a Cessna 182 at 10:36 a.m., NORAD said.

The single-engine, high-wing plane, which was out of radio contact, left the temporary flight-restricted area and landed at the Carroll County Regional Airport in Westminster, Md.

In the second of Saturday’s incidents, a Cessna 210 was intercepted by two F-15Es at 6:56 p.m. That plane also landed at the Carroll County field, where it was met by law enforcement officials, NORAD said.

In Saturday’s first incident, a general aviation aircraft was intercepted at 12:17 p.m., NORAD said. It also landed at Westminster, where the pilot was questioned, a Secret Service spokesman said Saturday.
