A Berks County, Penn., man was arrested Friday after authorities say he repeatedly raped a mentally disabled woman over the span of two years.

The District Attorney's Crime Unit arrested Joseph Lombardo, 59, at his Reading home on Friday morning, after an investigation dating back to September.

The District Attorney's office says that Lombardo sexually abused the 48-year-old woman numerous times between 2009 and 2011.

Authorities say he owns a transportation business called "Life Coach Companion" that transports mentally disabled people. Lombardo drove the woman to Special Olympics events.

He was not contracted by the Special Olympics and was paid $20 a trip by individual clients, including the woman's mother.

The sexual assaults happened in his vehicle and at his home, according to the District Attorney's office.

He is currently awaiting video arraignment at the Berks County Sheriff's Department.

Today's reading from the world of investigative reporting.

Story of the day:A Dayton Daily News investigation has found that "complaints of misconduct against nurses are taking more than a year for the Ohio Board of Nursing to investigate — allowing some of the nurses to continue to care for patients while under investigation…and the number of complaints against nurses is climbing, causing the backlog in investigations before the state nursing board's disciplinary system." A review of data found an inefficient system that worsened a problem it had not begun to solve: " The board received 6,880 complaints in fiscal year 2011, which ended June 30, putting it on pace for a double-digit increase in the state's two-year accounting period. In the previous two-year period, there were 11,645 complaints. That number was 34 percent higher than from 2007-2008. These complaints include allegations of substandard practice, drug theft, substance abuse, patient abuse and other criminal conduct."
