A burglar broke into a Manhattan penthouse early Tuesday and made off with a briefcase and an iPad belonging to a banker who once did work for President Trump’s former campaign chairman, Paul Manafort, the police said.

The homeowner, David Fallarino, 38, is a loan officer at Citizens Bank who handled loan paperwork for Mr. Manafort, who was convicted last week on federal financial fraud charges related to his overseas lobbying work.

Mr. Fallarino, who was not implicated in wrongdoing, called the police around 3 a.m. on Tuesday after discovering the break-in at his apartment on West 58th Street near Central Park, the police said. He told investigators that he was awakened two hours earlier by the sound of his front door slamming, the police said.

Mr. Fallarino told investigators he found a crowbar on his private terrace and discovered that the briefcase, the iPad and a pair of sneakers were missing from the living room, the police said. There were no signs of forced entry; Mr. Fallarino said he had left the terrace door open, the police said.
