The 26-year-old 'Liz & Dick' actress had filed a police report claiming she was choked and thrown to the floor by Christian LaBella after she confronted him for taking pictures of her in a New York City hotel room in the early hours of this Sunday morning.
But a New York City Police Department source told US gossip website TMZ that all charges have since been dropped against the 25-year-old young man.
Christian had initially been charged with two misdemeanor counts of assault and two counts of harassment.
Lindsay - who has been jailed countless times for charges stemming from DUI (Driving Under the Influence) and misdemeanor possession to grand theft - was earlier said to be determined that Christian was prosecuted to the fullest extent of the law.
The actress claimed the young man befriended someone in her group at 1 Oak nightclub with the intention of getting closer to her.
She said they later got into a heated physical argument after she found out he had taken more than 50 photographs of her and was emailing them to his friends.
Lindsay reported the incident to police at 4:30am and alleged she was choked from behind and thrown on to the ground in her room at the W Hotel in Manhattan where she was staying with friends.
