Melbourne park death 'not suspicious'

The death of a woman whose body was found in a suburban Melbourne park is not being treated as suspicious.

Police were called to St Kilda Botanical Gardens about 6.40am on Tuesday following the discovery.

An investigation was launched but a Victoria Police spokeswoman later told AAP the death has been ruled non-suspicious.

The gardens were cordoned off and closed to the public.

There was a strong emergency presence, with SES workers erecting a tent as detectives and forensic specialists surveyed the scene.
