"He had bandages around [his] neck and face because he had a medical procedure," the source added. "So, he was bandaged up when she [allegedly] choked him."
"All he did was answer a door to a knock," the source continued. "He didn’t know who was behind the door and then he was attacked. It was very scary for him and he was shaken up."
"She [allegedly] forced her way in, strangled him and ripped his shirt and ripped the bandages on his face," the source claimed, noting the attacker — who was identified as a 47-year-old woman by the name of Electra Schrock — also reportedly "squirted something on [Charlie’s] car and dumped trash on his property."
As OK! previously reported, the woman was said to have returned to her home after the altercation where she was eventually arrested by L.A. authorities. Although Sheen did call 911 and paramedics arrived at the scene, he was not taken to the hospital.

This comes not long after Sheen opened up on his decision to give up drugs and alcohol for good after years of publicly struggling with substance abuse issues.

The source spoke with Us Weekly about Sheen's attack.
