RCMP say the search for a missing man on Nova Scotia's eastern shore will only continue during the day after two searchers were injured overnight due to rough terrain.

Overnight, a helicopter used infrared technology that detects body heat to search from the sky for 61-year-old Wayne Baker of West Jeddore. A second chopper was back in the air today after fog cleared.

It's warm for this time of the year and that is in Baker's favour.

Police said they were called around 9:20 a.m. Monday after Wayne Leonard Baker, 61, was reported missing from his West Jeddore Road home. RCMP said he was last seen at his home around 4:45 a.m. Sunday.

They believe he left home on foot with a sandwich and a bottle of water.

Police and searchers say the six-kilometre search area consists of thick brush. Eighty people from several teams were on the night shift searching Tuesday. Some drove three hours to help.

Searchers say the area can be dangerous to search because of debris from Hurricane Juan.

Police describe Baker as a white man with long dark hair, a moustache and goatee. He is five feet, eight inches tall and was wearing blue jeans, black sneakers, a ball cap and possibly a green hooded sweatshirt. They say it's extremely unusual for him to be away from home for this long.

Anyone who has seen Baker is asked to call police at (902) 244-7208.
