Blake Reign, 27, was allegedly seen by several witnesses pleasuring himself at the Starbucks on Collins Avenue and 29th Street around 9:30 a.m. Friday.

Witness Alyssa DiMaria said she was in the shop when she used her phone to record him. DiMaria said he did it for about 10 minutes before officers finally arrived. At that point, Reign took off running, according to the arrest report.

Reign allegedly refused to comply with cops’ orders, and they shot him with a dart-firing stun gun. That’s when he got to yanking again — this time pulling the darts out of his body and running off again.

One of the officers was injured after he fell during the foot chase.

He is charged with lewd and lascivious behavior, disorderly conduct in an establishment, and resisting an officer without violence. His bond has been set at $700.
