A man in Sheffield is reported to have been filmed assaulting an XL bully dog despite being banned from keeping animals, according to accounts that reference CCTV footage. The footage allegedly shows Mason Sestanovich kicking and slapping the dog, described as “Chicago,” in the hallway of a block of flats. The dog reportedly appears distressed and cowers during the incident. The reports say the man was subject to an animal-keeping restriction at the time of the assault. The coverage is based on the CCTV material and accompanying claims about the ban. All outlets describe the same central events: the alleged dog attack captured on video, the location in a Sheffield residential building, the identification of the dog and the man, and the assertion that he was not permitted to keep animals when the incident occurred. The reports do not provide further procedural details beyond the existence of the ban and the publication of the footage. Authorities are said to treat the incident as an animal cruelty matter.
