An Attleboro man spent two months in jail after police found a balloon in his car with 54 grams of white powder in it last November.

But a later test found that Savath Soeu, 37 of Attleboro, was carrying a stress balloon filled with cornstarch and not heroin as police initially thought, according to The Sun Chronicle.

Soeu was stopped in November for driving with a suspended license when police found the balloon, according to the newspaper.

An initial field test showed a preliminary positive for heroin. He was charged with drug trafficking, according to the newspaper.

“My life was just hanging there. I didn’t know what was going on. My heart just dropped. My stomach just dropped,” Soeu said in an interview with The Sun Chronicle Thursday.

His 11-year-old daughter had made the balloon, which had a smiley on it and was filled with cornstarch, according to the newspaper. It is something she learned out YouTube Soeu’s family said.

All narcotics seized are taken to the state laboratory to be tested before going to trial, but the lab is backlogged, the newspaper reports, citing prosecutors and defense lawyers.

“I feel vindicated. I’m relieved that I’m done with that part,” Soeu told the newspaper.
