In police reports obtained by PEOPLE, Unruh's son, now 20, told authorities that he was "texting and snapchatting" when Spacey reached down his trousers and repeatedly touched his genitals over the course of three minutes while they were together at the Nantucket bar, where the accuser worked as a busboy.
Reuters reports that Mitchell Garabedian, the attorney for the alleged victim, said his client put in paperwork this week to drop his civil complaint against Spacey that accused the actor of "explicit sexual behavior and lewd and lascivious conduct". While he still faces criminal charges, the civil suit against him has been dismissed.
On Friday, the accuser's lawyer Mitchel Garabedian said the alleged victim filed a voluntary notice of dismissal Wednesday in Massachusetts Superior Court, just over a week after the suit was filed.
Spacey, whose real name is Kevin Fowler, has been charged with indecent assault and battery. He said he wouldn't discuss this further, according to The Los Angeles Times. A telephone message was also left at his office.
Actor Kevin Spacey, with his lawyer Alan Jackson at his side, is arraigned on a sexual assault charge at Nantucket District Court in Nantucket, Massachusetts, U.S., January 7, 2019.
In it, the accuser said Spacey bought him "multiple alcoholic beverages" before he then forcibly touched and fondled his genitals - the same allegations he made in an ongoing criminal case.
The criminal case has centred on the cellphone used by the 18-year-old the night of the alleged groping.
The lawsuit was filed against the actor in the Nantucket courthouse last month.
She accused Mr Spacey of buying her then 18-year-old son alcohol - the drinking age in MA is 21 - and then groping him.
"We're operating with very little info, but it's clear something unusual is going on here", he said. The judge has ordered the accuser, his parents and Garabedian to attend a hearing on Monday if it can not be found.
