One suspect has been arrested and another is being sought in the robbery of an elderly woman outside Parx Casino in Bensalem earlier this week.

Bensalem police said Friday that 33-year-old Jason Ballard had been taken into custody in the Sunday robbery. He faces charges that include robbery, theft and conspiracy.

Investigators have obtained an arrest warrant for the second suspect, 31-year-old Miguel Soto, but are still looking for him.

Both men are from the Newark, N.J., area, police said.

The two are accused of following a 73-year-old woman from the casino into the parking lot, where they grabbed her purse, making off with money and her cellphone.
