ALLENTOWN, Pa. - The Allentown Police Department has released a roughly 9-minute new video of the incident Saturday night that has spurred protests in the city.

The video was captured from a vantage point across the street, city police said in a news release. At one point during the incident, an officer had his knee on the man's shoulder and head, according to a use-of-force expert.

During the first four minutes of the video a person can be seen who appears to be suffering from a medical, mental health, or drug and alcohol crisis, city police said. He appears to vomit multiple times and he is observed to drop his cell phone and he appears to have trouble walking and standing, police said. Two officers who were at the hospital on an unrelated matter can be seen interacting with the distressed person in an effort to direct him towards the emergency room entrance, according to the release.

The next portion of the video shows a physical interaction between the person, police, and hospital staff, police said. 23 seconds of this portion of the video is reflected on a video which has been circulating on social media. During the interaction, a breathable spit mask is placed over the person's head, police said. The mask is used to protect hospital staff, officers and others from coming into contact with bodily fluids such as vomit and saliva.

The final portion of the video depicts hospital staff and police escorting the man into the hospital. He received treatment and was later released, police said.

The police department and the county district attorney's office continue to investigate the incident. Witnesses are being interviewed and evidence is being collected.

The Lehigh County District Attorney continues to investigate, and will release a statement when his review is complete, which is not anticipated until late this week, according to the release.
