"Most people's lives are in their phone," Jourdan said in court.A Customs and Border Protection spokesman was unavailable Friday due to the federal government shutdown.The incident began Wednesday when Adeyemi tried to enter Canada, but was turned back. After he was questioned by U.S. border agents he was told he was free to go, but they refused to return his phone. He refused to leave without it.The federal agents called the state police who initially charged him with trespassing. Assistant Orleans County State's Attorney Michael Cricchi told the judge that an assault charge was added because Adeyemi grabbed the wrist of a state trooper.Adeyemi was held overnight before he was released on an unsecured appearance bond.
