First responders and Good Samaritans are being hailed heroes for saving a woman in her 20s from the Detroit River late Monday night.

That woman, two police officers and an EMT were all brought to the hospital to be checked out for hypothermia. Police say the woman was alert and breathing when she was brought in last night.

We've learned the officers and EMT are now in stable condition.

It all happened around 10:45 p.m. at Riverside Park.

A fisherman spotted a woman in the water, struggling and pleading for help. Detroit police say he and several other Good Samaritans initiated the rescue.

"As a Good Samaritan, he attempted to help her, used his jacket... got assistance... until police responded,"said Rodney Cox of the Detroit Police Department.

Once police arrived, they jumped in with an EMT to save her. The Westcott Mail Company, a mail service for the freighters, also helped out.

Police say this may have been a suicide attempt. We're told the woman was nine months pregnant and a Caesarean section had to be performed to save the baby.

No word yet on the condition of the mother or baby.
