A suspected hand grenade found outside the Royal Melbourne Hospital is now believed to be a toy.

Police confirmed they were in Parkville following reports of a "possible suspect device" on Grattan Street just after 4pm and conducted a safety check.

Royal Melbourne Hospital staff were asked to keep people inside as a precaution.

After initial reports the device was a hand grenade, a spokesperson from the Metro Fire Brigade later confirmed the device to be a toy.
