A new surveillance video obtained by TMZ shows Lane Garrison slapping Ashley Mattingly across the face after he waited for her outside her apartment.
Lane was arrested for domestic violence Saturday, but denied hitting his ex, saying he put his hands on Ashley's shoulders, put her in a chair, and left.
Not exactly the case, according to the surveillance video:
The former Prison Break star claimed that he ran into his ex while visiting someone else's apartment, too ... but he appears to be sitting outside waiting for her.
When Ashley drives into the building's garage, Lane is seen stumbling as he runs after her. They are then seen walking into the building together.
Clearly arguing as they get into an elevator, Ashley seems to be asking Lane to leave, but when he refuses, she gets off ... and all hell breaks loose.In the apartment lobby outside the elevator, Lane is seen grabbing Ashley's arm with his left hand ... and then slapping her face with his right.
After a few more seconds of struggling, Lane bolts. He can then be seen throwing what may be Ashley's phone into the street, then leaving for good.
Garrison was arrested for felony domestic violence and is being held on $50,000 bail. He is on a parole hold because of his manslaughter conviction.
With just six days left on his parole (he killed a teenager in a DUI five years ago), he could face additional prison time based on this arrest.
It remains to be seen if he will face charges from this in the long run, but his initial defense certainly isn't helped by what the video shows.
