Police are hunting a man wearing a clown face balaclava who attempted to rob a Deliveroo driver during his round in Aylesbury.
The attempted theft happened at 8.30pm on Sunday February 24 in Thame Path.
The victim, a 35-year-old man, was delivering food just off Churchill Avenue.
He was on a path on his bicycle that runs parallel to Prebendal Avenue when a man stepped in front of him and grabbed hold of his Deliveroo bag, stating that he wanted the contents.
The thief then verbally threatened the Deliveroo worker, who started shouting before fleeing the scene.
