A Wrentham man who previously pleaded guilty to fraud-related charges linked to renovations to a Boston federal building was arraigned Thursday in his second child pornography case.

Wael Isreb, 66, pleaded not guilty during a remote arraignment in federal court in Boston to a charge of possession of child pornography, records show.

A lawyer for Isreb, who was initially arrested in August and later released on pretrial conditions, declined to comment.

A federal grand jury indicted Isreb last week, records show.

In 2014, Isreb was sentenced to four years of probation in the same courthouse after pleading guilty to conspiracy to commit mail fraud and false statements in a scheme related to renovations to the John W. McCormack Post Office and Courthouse in Boston.
