HOUSTON -- Authorities in Houston say more than 100 burglaries of Houston-area pharmacies have occurred since June.

The thefts have resulted in the losses of millions of dollars worth of prescription drugs.

Ten people have been charged in the burglaries and authorities say at least 20 others are believed to be involved.

Officials say most of the burglaries are targeting "mom and pop" pharmacies where drugs such as Soma, Xanax, hydrocodone and codeine-based cough syrups have been stolen.

The drugs are being found by authorities in traffic stops around the state and the country.

Police have declined to release the names of those already charged in connection with the burglaries, citing the ongoing investigation.

No one has been injured in any of the burglaries.

Crime Stoppers is offering up to a $5,000 reward for information leading to the identification, arrest and prosecution of people involved in the burglaries.
