An assistant professor at the University of Houston Clear Lake campus was arrested and charged with making threats on campus.
Lei Wu has been an assistant professor of software engineering since 2008.
According to court documents obtained by Local 2, Wu told another professor he wants to make tenure and said there would "be blood."
"It is something that happened on the U of H campus and something my office is taking very seriously," said William Mejia, the Harris County District Attorney.
Investigators said Sharon White, who works with Wu, was on the receiving end of the threat and that she feared for her life and for the safety of her co-workers.
Investigators said the threats were made not only against White, abut also members of the tenure board.
When White asked Wu to clarify what he meant, court documents show he said, "it will be bad for either" decision and "both will be blood."
The two professors have reportedly had problems in the past, so investigators said White brought along a recorder when Wu asked to speak with her.
The conversation is now in the hands of the assistant district attorney, who is handling the case.
"Our full focus is ensuring her safety and making sure all evidence is preserved," Mejia said.
