HOUSTON -

A woman has been accused of sending more than 100 sexually-explicit messages to another woman on Facebook.

Houston police said Tenika Lynn Mayfield helped her grandfather at a welding job at Excel E Care on the North Freeway in June.

Detectives said Mayfield became obsessed the Deavra Daughtry, the owner of the health care center.

Mayfield started posting personal messages to Daughtry on her Facebook page in July, police said. Some of the messages were sexually suggestive and others were threatening, officials said.

"You know, I do know where you work at and I do know you will be there by yourself until late sometimes," one of the messages read, police said.

"I will hear from you next week, even if I have to come to your house," another message read, according to authorities.

"When I do get you, and I do mean get you, it is going to be on," another message read, police said.

Police said Mayfield posted more than 170 messages.

Mayfield also followed Daughtry, confronting her at her job in January and at a children's party in February, investigators said.

"The complainant was very confused about where all this came from," Assistant Harris County District Attorney Natalie Schultz said. "She was definitely in fear of physical or sexual assault, and she had the police intervene."

Police said they contacted Mayfield in March and warned her to stop harassing Daughtry, but the messages did not stop.

Mayfield has been arrested and charged with stalking. She is being held in the Harris County Jail with bond set at $5,000. If convicted, she could face up to 10 years in prison.

Daughtry declined to talk about the case. Her attorney, state Rep. Sylvester Turner, said she is shaken up and she and her children want to put all this behind them.
