(CNN)Corey Feldman took to Twitter Tuesday night to say he had been hospitalized after being stabbed.
LAPD Officer Drake Madison told CNN they are investigating an incident involving Feldman.

"IM IN THE HOSPITAL! I WAS ATTACKED 2NITE! A MAN OPENED MY CAR DOOR & STABBED ME W SOMETHING! PLEASE SAY PRAYERS 4 US," Feldman tweeted. "THANK GOD IT WAS ONLY MYSELF & MY SECURITY IN THE CAR, WHEN 3 MEN APPROACHED! WHILE SECURITY WAS DISTRACTED, W A GUY A CAR PULLED UP & ATTACKED! I'M OK!"
An LAPD spokesperson told CNN the incident is being investigated as "an assault with a deadly weapon."
According to a spokesperson for Feldman, he was stabbed with what they believe to be a syringe.
"We are waiting on tests to make sure he is not injected with anything like a poison or a virus," Feldman's publicist told CNN.
Feldman was released from the hospital Wednesday morning, his publicist said.
