A man suffered facial injuries when he was sprayed with a "non-corrosive" liquid in London.
The victim, believed to be in his 20s, was sat in a stationary car near Kingston railway station when two attackers on mopeds threw the substance before escaping. Nothing was stolen.
Emergency services were called to Fife Road at about 12.30 BST on Tuesday.
The man was not seriously injured, but was taken to hospital as a precaution. No arrests have been made.
