An elderly man is in critical condition Sunday after his car plunged into a canal in Hialeah.

Hialeah police Sgt. Eddie Rodriguez said the car plunged into the canal near the 6500 block of West Fourth Avenue just before 7 p.m. Saturday.

Police say another man nearby jumped in the water and tried to help but was unable to get the man out of the car.

A rescue diver did pull the man out and he was taken to the hospital in extremely critical condition.

One woman on the scene said the car was moving slowly when it slipped into the water. There were no tire tracks on the road or the banks of the canal.

Police are also interviewing the Good Samaritan for clues.

“He’s our key witness he was closest to the vehicle when the accident occurred and he’s helping us with this investigation,” said Sgt. Rodriguez.

Police have not released the name of the elderly driver.
