BILLINGS, Mont. (AP) — A Billings man awaiting trial on allegation that he put methamphetamine in a coffee maker at his mother's tax preparation business is back in jail.

Prosecutors allege 34-year-old Craig Charles Benedict violated the terms of his release by failing to submit to random drug tests.

The Billings Gazette reports District Judge G. Todd Baugh set Benedict's bond at $15,000 on Monday.

Benedict posted a $10,000 bond following his February arrest on felony criminal endangerment charges. Court records allege Benedict spiked the coffee because he was angry that another employee at the tax business demanded that he submit to a drug test.

Prosecutors say nearly a dozen people may have consumed the meth-laced coffee.
