Charges were pending for someone who allegedly pushed a 35-year-old man down a flight of stairs early Monday during a fight at a River North restaurant, police said.The 35-year-old tried to intervene in the fight between a man and group of people that occurred around 1:20 a.m., at 110 W. Hubbard St. , when another man pushed him down the stairs, Chicago police said. A multistory building located at 110 W. Hubbard lists at least one nightclub and a restaurant.The man, identified as a security guard by a law enforcement source, was taken to Northwestern Memorial Hospital, where he was pronounced dead, police said. Officers who responded to a 911 call from the Hubbard Inn, arrested a 32-year-old man who allegedly pushed the victim. Hubbard Inn is owned by Carmen Rossi, a lobbyist, lawyer and city contractor who owns many bars and restaurants through his hospitality group, 8 Hospitality. He has had troubles with the city and his bars have come under scrutiny because of violence concerns in recent years.Rossi didn't respond Monday to requests for comment, but Hubbard Inn will be temporarily closed in the coming days, a spokesperson said in a statement. Staff will be paid during the closure and external help will be hired for private events if Hubbard Inn staff aren't ready to come back to work."The Hubbard Inn team is devastated by last night‘s tragic incident and our hearts are with the family who lost their loved one," the spokesperson said. "We can’t comment on the specifics as the work of CPD is ongoing, but we are closing our doors to the public for the next couple of days while giving staff time to grieve and provide access to mental health support to those who may need it."Former Mayor Lori Lightfoot returned campaign contributions from Rossi's businesses after the Chicago Sun-Times reported she took the money despite a ban on mayors taking money from city lobbyists. Shortly after, Rossi paid a $5,000 fine for breaking lobbying rules by trying to secure business licenses to operate parking lots on Chicago Public Schools property when he wasn't registered as a lobbyist with his company Chicago Parking Solutions.Rossi also benefitted from Mayor Brandon Johnson's administration at City Hall. Along with his business partners and clients, Rossi gleaned $38.5 million in deals under Johnson. He is no longer registered as a City Hall lobbyist, but he is registered to lobby state lawmakers in Springfield and owns a cannabis startup that has converted a bank building in suburban Bolingbrook into a dispensary.In 2024, The Hubbard Inn was the site where a woman posted a viral video claiming she was manhandled by a security guard and thrown down stairs. A judge later dismissed nearly all of the accusations she made.In 2021, a patron of one of Rossi’s nightclubs, LiqrBox, in the 800 block of North Orleans Street, was shot to death outside the bar. Five days later, a customer reported being sexually assaulted inside the same bar by an employee.Also in 2021, a man was wounded in a shooting outside Joy District in the 100 block of West Hubbard Street. ...read more read less
