Jon Gosselin’s Manhattan apartment was vandalized over the holiday weekend. After spending the holidays with his brood in Pennsylvania, the Octodad and former star of TLC’s Jon & Kate Plus 8 returned to his New York City apartment to find it burglarized and vandalized, his lawyer confirmed to The Associated Press Saturday.

”[Jon] entered his apartment in Manhattan and was horrified, disheartened, and saddened to observe the devastation of his furniture, clothing and personal belongings, which were apparently slashed with a butcher knife by a very troubled and sick perpetrator,” Gosselin’s lawyer, Mark Jay Heller, said in the press release. “Jon immediately contacted me and facilitated the able assistance of the New York City Police Department who immediately dispatched an experienced Detective to Jon’s apartment, where a forensic team commenced an intense investigation including photographing and fingerprinting of evidence at the crime scene,” Heller continued.

Gosselin’s television, CD player, a Nintendo Wii game and some kitchen items were stolen from the apartment. Several items of clothing, bedding, and other furnishings had been slashed with a butcher’s knife, according to the attorney. And sources say a note was left behind with Hailey Glassman’s name signed at the bottom.

“The police department seized a note that had been affixed to Jon’s bedroom dresser by a butcher knife that was speared through the note into the wooden dresser. The note will be forensically analyzed by a handwriting expert,” the statement continued. “At this time, I will not release the contents of the note or the signator, however, both Jon and I have determined that the perpetrator must be vigorously prosecuted on felony charges.”

Heller characterizes the incident as “cold-blooded.”

“Sadly, along with the trashing of Jon’s apartment, a Ming vase, believed to be over 100 years old that was a family heirloom, was smashed to pieces,” he said. “The greatest damage from this vicious, mean spirited and heartless crime was perpetrated not on Jon’s property and possessions, but on Jon Gosselin himself, who experienced a traumatic, emotional, roller coast ride having just shared a joyful family gathering with his children during their Christmas Celebration and the last thing that Jon contemplated when entering his New York City apartment, on what is suppose to be a Season that heralds in peace and goodwill, was to be devastated by such a cruel and cold-blooded act that was apparently intended to cut to his heart.”
