What are laws for minors who run away in Pennsylvania?

I ran away several different times at the age of 15. And the police station got involved two of the times. The police station told me that if I ran away a third time and they were involved than my most likely option would be, being sent to a group home. I dont know if this is the LAW, a SCARE TACTIC, or something PARENTALLY involved, but this is what i was told.
