The Wayne County sheriff's department says it has released 55 people arrested earlier in the week when authorities busted what they described as a major dog fighting ring in Detroit.
The Detroit News reports that the department and the prosecutor's office failed to meet a 48-hour deadline to formally charge 52 men and three women police arrested early Monday on the city's east side.
The Wayne County prosecutor's office says warrants were issued for 12 people, including six suspected ringleaders, and court dates will be set within the next two weeks. Others were warned they likely will face court dates.
Authorities say the arrests came at the start of a fight between two pit bulls. One dog was caught and the other escaped.
