WESTPORT — A Westport man accused of spraying toxic chemicals in his female neighbor’s yard and shining floodlights into their house has now been charged with tampering with physical evidence involved in a police search of his home.

On Sept. 12, Westport detectives arrested Sterling Drive resident John Borg, 49. Police previously received a search warrant for Borg’s cell phone, which was seized at the time of his arrest. Borg was advised of the search warrant for the contents of his phone, but when investigators attempted to search its contents the following day, they found the phone had been remotely wiped and all of the contents deleted, police said, adding they submitted a warrant for Borg’s arrest.

On the same day police seized Borg’s phone, they also executed a search warrant of Borg’s home, which he shared with Alison Borg, police said. During the course of the search, Alison, 46, was allegedly uncooperative and refused to allow investigators access to various parts of the home, including an attached garage and home office.

For about an hour, investigators attempted to reason with Alison and convince her to provide access to the spaces, but she refused, police said. Alison lied to detectives saying she did not have access to the attached garage or home office, whose doors bore the name “Many Gates,” a business with which Alison said she had no affiliation, police said.

An online search showed Alison Schor was the president, secretary and treasurer of the Many Gates Healing Arts Center, P.C, of Westport and that Schor is Alison’s maiden name, police said. When detectives were able to access the office space, they observed certificates for Alison Borg and John Borg, and there was no evidence that space was used by anyone else but the Borgs.

Police eventually forced entry into the garage, which housed a car registered under the name of Alison’s business. Alison’s phone was also seized and searched as part of the warrant. The phone allegedly contained photographs of the inside of the attached garage and basement office, though she claimed not have access to these spaces.

Then on Oct. 4, officers dispatched to a Westport residence on a report of ongoing harassment. John Borg erected three stadium-style lights, which were pointed directly at the same female victim’s property. The lights were activated three different times that evening, the victim said. Borg was previously arrested for similar incidents of harassment against the victim, and he was the respondent of an active protective order prohibiting him from harassing her at the time of the Oct. 4 incident, police said.

On Oct. 17, Borg turned himself in at police headquarters on the outstanding warrant and was charged with public disturbance, two counts of criminal violation of a protective order, and tampering with or fabricating physical evidence. Borg was held in lieu of $30,000 bond for the first two charges and $50,000 for the third charge. Borg was transported later that morning to state Superior Court in Norwalk, where officers observed Alison Borg sitting in the courtroom.

Alison was arrested on the outstanding warrant for her arrest. She was brought to Westport police headquarters and charged with interference with a search and released after posting $10,000 bond. Alison Borg was scheduled to appear in state Superior Court in Norwalk on Oct. 24.
