A 60-year-old shopkeeper was left bloodied after a group of five youths descended upon his kiosk on Swanton Street in Melbourne's CBD.

Senol Kocabiyik, who was often in tears while recounting the incident, said the group of youths started rummaging through his stock at about 9.30pm on Friday.

"They tried taking chocolates, lollies, electronic Hookah, mints, Tic Tac," Mr Kocabiyik said.

"When I said 'don't touch' they said 'f**k off".
