A Florida judge dropped all criminal charges against former UFC light heavyweight Thiago Silva on Thursday, effectively clearing him from an alleged domestic violence incident involving his ex-wife.

Silva, 31, was arrested Feb. 6 and initially charged with two counts of attempted murder after he allegedly threatened his estranged wife, Thaysa, outside a mixed martial arts academy in Oakland Park, Florida. The next day, the charges were reduced to aggravated assault with a firearm.

A spokesperson for the Boward County Attorney's Office in South Florida confirmed to ESPN.com all charges have been dropped. TMZ reported the story earlier on Thursday.

"The victim had become increasingly uncooperative and investigators determined she has likely moved out of the country," the spokesperson said in confirming that charges were dropped.

At the time of his arrest, Silva (16-3) was scheduled to fight Ovince St. Preux at UFC 171 on March 15 in Dallas. UFC officials immediately announced the termination of Silva's contract. He fought 12 times for the promotion, dating back to 2007. On Friday, Silva's management team announced on Twitter that the UFC had re-signed Silva.

The Brazilian fighter was released on $25,000 bond in March and signed a contract with Fight Time Promotions in June. He was scheduled to fight Mike Hayes on Aug. 29 in Fort Lauderdale, Florida, but withdrew due to a knee injury.
