*Aretha Franklin’s son checked out of a Detroit hospital Tuesday where he underwent emergency oral surgery after being severely beaten by three people Monday night, said his mother’s spokeswoman, Gwendolyn Quinn.

Eddie Franklin, 52, had already left Sinai-Grace Hospital when investigators arrived in hopes of conducting an interview, Detroit Police Sgt. Eren Stephens said early Wednesday.

“We’re waiting for him to file a police report,” Stephens said. “When our officers went to talk to him at the hospital, he had already checked himself out and left.”

According to Quinn, two men and a woman assaulted Franklin, 52, near Plymouth and Evergreen. The female suspect appeared to be about 19 years old. One of the men had dreadlocks, Quinn said.

Detroit police, citing preliminary information, confirmed that Franklin was found at a gas station in the city. An acquaintance took Franklin to an area hospital, Stephens said. The person then told police what happened, she said.

Stephens didn’t release the identity of the person who helped Eddie Franklin.

There was no security video at the gas station to help investigators sort out the situation, police said.

“We have nothing at all,” Stephens said.

Franklin was a suspect in the Oct. 25, 2002 fire at his mother’s mansion in Bloomfield Township. He was cleared about a year later of setting fire to the 10,000-square-foot home.

Discrepancies in evidence and witness statements were credited with preventing investigators from seeking charges. A family attorney in 2003 told The News the decision not to issue charges vindicated Eddie Franklin.

Aretha Franklin has won numerous awards, including Grammys and induction into the Rock and Roll Hall of Fame.
