Apparently, Johnson strangled the woman until she blacked out and later threatened a security guard, telling him "I'll rip your f*cking vocal cords out."
The GF told police ... while Johnson was strangling her, she told him, "If you are going to kill me squeeze harder and just do it."
Johnson is being held on $15,000 bail on a battery with strangulation charge.
The woman told police she is an ex-girlfriend of Johnson's and that, in addition to being strangled, Johnson beat her. She also told police that she had been beaten by Johnson before.
After regaining consciousness, the woman was able to contact security, who held Johnson until police arrived. That is when Johnson allegedly made the comment to the security guard about ripping his vocal cords out.
The woman reportedly had marks on her face and neck, while Johnson had a a pair of small cuts.
Unfortunately, this is not a new situation for Johnson. He has been arrested four other times since 2003.
