(AP) — A reputed prison gang leader who was on probation in California has been captured in Missouri.

Forty-five-year-old Albert “Spanky” Amaya is jailed in Missouri’s Pettis County while awaiting extradition. No attorney is listed for him in online Missouri court records.

Amaya was sentenced to 25 years to life in state prison in 2008 after he was convicted of extortion, his third felony conviction. But he was released in June after a voter-approved measure allowed inmates sentenced under the state’s three-strikes law to seek re-sentencing.

The San Bernardino County probation department placed him on GPS monitoring while seeking to send him back to prison. Authorities allege he was a crew chief for the Mexican Mafia prison gang and fled after cutting the GPS device.
