All apparently did not know their attacker, but the attacker is known all too well by police. CBS is not naming the man accused of punching people as he hasn’t been formally charged, but CBS 2 dug into his lengthy criminal record.

He was arrested about 50 times in Cook County since 1993. Court records show he’s been in and out of jail for years. Past allegations include battery and criminal damage to government property.

And after Chicago police arrested him, that list is likely to grow. All the victims are expected to be OK. Police added the number of those victims could increase as the investigation continues.
