ATLANTA -- Authorities have raided Chris Benoit's doctor's office and the doctor's mother's home where he lives. DEA agents were on the scene of Dr. Phil Astin III's office in Carrollton.

Astin is the target of a federal investigation. It started as a Fayette County investigation related to the death of the Benoit family. Now, authorities said, it is a completely separate federal investigation which has prompted the second search warrant and the raids.

Officials used a battering ram to break into Astin's office.

Authorities told Channel 2's Ross Cavitt the raid is a follow-up to the previous raid on Astin's office Wednesday.

Chuvalo Truesdell with the DEA said, "We are following up on leads from the search warrant the other night."

Officials said they did not have an arrest warrant for Astin.

"We are investigating other leads that we cannot comment on at this time," said Truesdell.

Astin's office has been closed since Wednesday.

Channel 2 photographer Tracy Reeves reports DEA agents also entered Astin's mother's home. Reeves said he had been at the house all day and had seen no sign that anyone was home.
