LEMON GROVE - Four adults were back in custody Wednesday following a hours-long crackdown on East County parolees and probationers with ties to auto theft-related crimes, authorities said.

The four were taken into custody Tuesday morning, each on suspicion of a different felony, ranging from weapons and drugs crimes to auto theft, according to San Diego County sheriff's Sgt. James Blanton.

Around 7 a.m. Tuesday, some 40 deputies and probation officers set out to check on 22 probationers and parolees living in Lemon Grove and Spring Valley, the sergeant said in a statement. The sweep lasted until noon.

All 22 of the probationers and parolees have a history of auto theft-related crimes and were targeted because of an increase in such crimes in the area, Blanton said.

The names of those arrested were not immediately released.
