Police said they've arrested a man on parole for aggravated assault in connection with a series of armed robberies outside Pittsburgh.
Rodney Edward Michael was charged Friday with attempted homicide, robbery, theft and aggravated assault in connection with the Ambridge robberies.
Police said the 28-year-old attacked two men at knife point in separate incidents Wednesday and threatened two men with a BB gun during a robbery Friday.
Michael is jailed in lieu of $100,000 bail. Court records didn't list a lawyer for him. A preliminary hearing scheduled for Dec. 11.
Police say Michael put a knife under a man's chin and demanded money and stabbed a 60-year-old man at a bus stop on Wednesday and stole a cellphone, $70 in cash and some prescription pills on Friday.
