A Sheffield barista who was assaulted as he opened up to start his shift has sparked a police probe.
Officers were called to reports a 24-year-old man was assaulted in a 'unprovoked attack' by a 'Polish speaking' man around 10am on Sunday, October 16 in Orchard Square, city centre.
The employee, who doesn't want to be named, suffered a swollen eye and told The Star the incident had left him shaken.
The 24-year-old said the man pictured in the CCTV image is the same person who attacked him.
The barista said: "These two guys came in with coffee cups from a different shop and I asked them politely to leave but they soon started being abusive.
"I told them to leave again and I rang security. I walked around the counter and one of the men punched a chalkboard in my face - it was completely unprovoked."
The employee was left with a black eye and called the police shortly after who came in the day after to collect a statement.
The man in question is said to have returned to the store and threatened the barista again in Polish.
"It shook me up, I didn't feel like I wanted to return to work, I didn't feel safe.
"No one can do their job properly if they're being threatened or assaulted."
A South Yorkshire Police spokesman said: "Officers were called at around 10am on Sunday, October 16 following reports of an assault at a coffee shop in Orchard Square in Sheffield city centre.
