Police believe two men arrested in Alpharetta after a chase that injured a police dog Oct. 8 could be the same suspects who earlier stole phones from Sprint and AT&T stores in Roswell.

Enock Louis, 26, and Courtney Blake Jr., 19, both from Florida, were arrested after a high-speed chase in Alpharetta that led both men and the police dog, Mattis, to jump off a 30-foot wall. Police said they found dozens of cellphones, credit cards and IDs.

Due to the similarities, authorities believe the Roswell thefts may be related. Workers at the Sprint store said a man matching the description of Louis broke the security seal on the phones and ran out with them. At the AT&T store, police say the same thing happened with another suspect.

The evidence officers say ties this crime to a chase that hurt a police dog.

Alpharetta Department of Public Safety Officer George Gordon said Mattis, who suffered internal injuries, is doing well after surgery but will be out of service for four weeks.
