"Meet Ahmed Mohammed. He might be the most expensive hot dog vendor in New York, especially if he thinks you're a tourist," begins NBC 4 New York's investigation into a World Trade Center-area food stand the network caught on camera charging anywhere from $3 to $30 for a hot dog.

The investigation was launched after five fights reportedly broke out by the stand in the past week. Mohammed allegedly has been asking for the outrageous amounts of money after customers are already served, and sometimes, have even taken a bite. When asked why his prices fluctuate so drastically, he claimed to not speak English.

The Department of Consumer Affairs requires vendors to post their prices, and Mohammed's, NBC 4 reports, were not. They also note that a cart around the corner lists hot dogs for $1.

Anyone who encounters a stand with no price listed, or is charged more than the posted price, should file a complaint with 311. The DCA told NBC 4 they are investigating Mohammed.

On Wednesday afternoon, officers from NYPD Precinct 1 paid Mohammed a visit. A post on Twitter said they served him with three summonses.

"@JessLappin What? A $30 hot dog?! We paid him a visit. 3 ECB summonses. #PostYourPrices #WeWillBeBack @DowntownNYC," the tweet read.

It is not clear how much he was fined by cops.
