A Brooklyn man was arrested after a 5K run held in memory of a slain Sandy Hook Elementary teacher, accused of accosting the teacher's family and claiming the shooting in Newtown, Connecticut never happened. 

Police arrested Matthew Mills, 32, of Brooklyn, New York after the Victoria Soto Charity Run in Stratford, which honors the memory of the 27-year-old first-grade teacher who died while trying to protect her students during the tragedy in Newtown in Dec. 14, 2012.

After the event, Mills allegedly approached some family members and said the Newtown school shooting was staged and part of a conspiracy, according to Stratford police. 

When officers approached him, Mills tried to run, but police quickly detained him and charged him with breach of the peace and interfering with an officer, according to police. 

Mills posted a $10,000 dollar bond and is scheduled to appear in court on Nov. 17. He has an unlisted telephone number and could not be reached for comment.

The annual Victoria Soto Charity Run benefits the Vicki Soto Memorial Fund, a charitable organization established in honor of Soto and her passion for education. The fund has awarded more than $20,000 in educational scholarships to students pursuing a career in education.

Soto was among the 26 people shot to death at Sandy Hook.
