The grandmother of a 4-year-old girl who became hysterical during a security screening at a Kansas airport says security agents forced her to undergo a pat-down, and even yelled at the child and called her an uncooperative suspect.

The incident has been attracting increasing media and online attention since the child's mother, Michelle Brademeyer of Montana, detailed the ordeal in a public Facebook post last week. The Transportation Security Administration says its agents followed proper screening procedures.

The child's grandmother, Lori Croft, told The Associated Press on Wednesday that mother and daughter initially passed through security at Wichita's airport without incident. But then the child ran to briefly hug Croft, who was awaiting a pat-down after tripping the alarm.

That's when TSA agents insisted the child undergo a physical pat-down.
