It was his second arrest in three days, The St. Petersburg Times reported.
Michael Lohan was captured after he jumped from the third-floor balcony into a tree and then briefly fled officers on foot early Thursday morning. He was taken to Tampa General Hospital with what may be a broken foot, the newspaper said.
Michael Lohan was being kept in the hospital for monitoring until at least Friday morning, WTSP-TV, St. Petersburg, reported. Tampa police said he would be taken to jail once he was released from the hospital.
Police said the latest incident involving the star's father started just after 1 a.m. Thursday when they received a call from his on-again off-again girlfriend, Kate Major, who said he was harassing her by telephone.
Michael Lohan was arrested Tuesday on domestic violence charges involving Major, a former tabloid reporter, and was told to stay away from her when he was released from jail Wednesday night.
The newspaper said Michael Lohan told reporters Thursday Major had called him asking for help.
"She keeps doing this," he said. "She needs help, she calls me, and I'm a sucker so I call back. I'm an idiot."
