SEVERAL Victorian police are likely to face criminal charges over the treatment and subsequent death of a man after he was released from Dandenong police station this year.

The 53-year-old Chinese man died at Dandenong Hospital about 11.40am on May 13, some 15 hours after being discharged from the police station.

The Age understands homicide squad investigators have seized video footage from outside the station that shows about five police dumping the visibly ill man in a puddle upon his release while the temperature was about 12 degrees and raining.

It shows the officers standing over the man laughing and gloating about the state he was in and some policewomen can also be seen holding their noses because of the stench caused by the man soiling himself while in custody.
