Mohammad's father, Maher Suleiman, said his son does not speak.
Suleiman's father said a substitute teacher at the C.J. Harris Elementary School, which is located in Pearland, near Houston, made the call.
A U.S. teacher has branded Mohammad Suleiman, a six-year-old child with Down's syndrome, a "terrorist", FOX 26 News reported. "It's discrimination actually. It's not implied discrimination; it's 100 percent discrimination".
Child Protective Services investigated as well, he told KRIV. The Pearland Police Department did not immediately respond to a request for comment, but they told Fox26 they saw no need to get involved after briefly looking into the case.
CPS says its investigation remains open.
"The last three to four weeks have been the hardest of my life", said Maher.
"In my opinion, based on everything I heard from the police department and speaking with the administration from the school, that this was a story piecemealed together by a substitute teacher alleging this child was sexually harassing her, the teacher, and possibly being a terrorist", said local community activist Quanell X.
He went on to state that his 6-year-old son had intellectual difficulties and didn't speak.
Due to privacy laws, the Pearland Independent School District has not released any information pertinent to either the student or the personnel, according to a spokesperson.
This incident is not an isolated one. "It's unbelievable. I just don't get it", Carroll said.
"It was really sad that she took the wrong impression of it", he added. The police then announced that the teen wouldn't be charged. The controversial move has prompted harsh criticism on social media.
