Vandals using a stolen excavator caused thousands of dollars worth of damage chaos in the Adelaide Botanic Gardens overnight.
Police say the earthmover was stolen from a construction site next to the gardens about 2am.
About $30,000 of damage was caused when the thieves drove the excavator through archways, over garden beds and park benches before crashing it into the Botanic Gardens Café.
Graffiti was also found on the Cactus House, but it is not known if it is related to the excavator incident.
