An Arlington man who worked at a Newton day care has been arrested on accusations he shared child pornography via social media websites.

On Thursday, Mason Lister, 21, was arrested for allegedly possessing and distributing child porn, Fox25 reported. He was formerly employed as a maintenance worker at Family Access day care in Newton.

“We don’t have any information that would us lead us [to believe] he had any contact with the children at this point,” Arlington Police Cpt. Richard Flynn said to Fox25, which added that authorities were investigating where the images originated, but they do not think anything happened at the day care facility.

Lister drew the attention of officials when he allegedly shared the images on Dropbox, Kik and Twitter, according to CBS Boston. When investigators searched Lister’s computer, they found numerous images but did not specify the ages of the children depicted.

“The exploitation of children, the abuse of children, is one of the worst crimes in our society and we take it very seriously,” Flynn was quoted by CBS Boston. “Where the images came from [is] a big part of our investigation right now.”
