UNION, S.C. -- A Union couple released from jail earlier this year has been arrested and charged with robbery.

Twenty-six-year-old Matthew Williams and 23-year-old Porsha Sharday Gage were arrested Tuesday night at a Spartanburg hotel.

They've been charged with two counts of strong arm robbery, simple possession of marijuana and possession of cocaine.

It was not clear if the two have lawyers.

Union County Sheriff David Taylor said Williams and Gage were arrested in July 2011 and charged with strong arm robbery, attempted robbery and criminal conspiracy. They were sentenced to four years in prison and four years of probation. Gage was released on probation in January, and Williams was released in March.

Authorities in Greenville, Greenwood, Laurens, Lexington, Spartanburg and Union counties are investigating.
