A gunman is on the loose after a man was shot and injured in what police suspect was a failed hit in Melbourne's south-east.

The Hampton Park attack which occurred in Fulham Close about 9.30am on Tuesday is the latest in a string of fatal shootings across Melbourne.

Senior police sources have said homicide squad and anti-bikie Taskforce Echo resources have been strained in recent weeks following the spate of deaths.

Just days ago, Daniel 'Dodge' O'Shea was killed at Fawkner Park in South Yarra - his was the eighth fatal shooting in Melbourne in eight weeks.
