A former Boston banker has been accused of being a serial rapist who held most of his victims at knifepoint, including 13- and 14-year-old girls, and stabbed three of them, police said Tuesday. authorities.
Ivan Cheung, 42, has been charged with multiple counts of aggravated rape, rape of a child and other crimes that the Suffolk County District Attorney’s Office says occurred from 2003 to 2006.
Cheung, who has addresses in Boston and suburban Quincy, was held in lieu of $1 million bond after a Boston City Court appearance on Tuesday, NBC Boston reported.
A spokesperson for State Street, the Boston-based financial services firm, said Tuesday that Cheung had been terminated. A Linkedin profile that appeared to be Cheung’s mentioned his position with the company as vice president of sourcing category strategy.
In the first case, Cheung is charged with hitting on a 13-year-old girl in Boston’s Chinatown, the prosecutor’s office said.
He is accused of driving her to another location, where officials say he raped her with a knife and stabbed her in the shoulder, the statement said.
Cheung reportedly picked up a 14-year-old girl from the Charles Circle area a week later. He held a knife to her throat before raping her twice and stabbing her, prosecutor Ian Polumbaum claimed in court.
Two years later, Cheung picked up a 23-year-old near downtown Boston, the statement said. The prosecutor’s office said he held a knife to her throat before repeatedly raping and stabbing her.
He is also accused of picking up an 18-year-old in the city’s North End and holding a knife to her throat and raping her in 2006, the prosecutor’s office said.
Cheung was arrested after authorities launched an effort in April to reinvestigate 100 unsolved sexual assault cases in Boston.
Detectives followed Cheung to a mall this year and recovered his discarded cigarette, Polumbaum said. A male DNA profile obtained from the cigarette matched genetic material taken from sexual assault kits used in the 2005 and 2006 cases, Polumbaum told a judge.
Polumbaum said there were other “common threads” between the four cases, including the type of car the suspect used in the assaults.
Cheung’s attorney, E. Peter Parker, said in an email Wednesday that the allegations were “very old.”
“This presents complex evidentiary, factual and forensic issues for the prosecution, which we will all aggressively contest,” he said.
Cheung’s next court appearance will be on September 22.
