A Chicago man was caught on video stabbing his brother-in-law 25 times before partially disemboweling him on a city bus.

Darnell Scott, 37, is accused of attacking his 50-year-old brother-in-law after the two had an altercation on a city bus Thursday evening, according to the Chicago Tribune.

Police say Scott and the victim are related through marriage, but have a rocky relationship and haven’t spoken to each other in a while.

When Scott got on the bus Thursday evening and walked passed his brother-in-law without saying anything, the older man reportedly followed Scott to the back and confronted him.

Scott then started punching the man and onlookers began to film what soon became a bloody attack. After the two men ended up on the bus floor, Scott pulled out a knife and started stabbing his brother-in-law, partially disemboweling him in the process.

After the attack, the victim was taken to the hospital and listed in critical condition.

Incredibly, he is expected to survive his injuries, according to Fox News.

The 50-year-old reportedly told police that Scott started punching him after he asked Scott if he had sent people to “jump him” previously.

Scott, who was also hospitalized for his injuries, was arrested after getting off the bus and charged with aggravated battery. He was denied bail on Saturday and ordered to have no contact with the victim.

Cook County Judge John F. Lyke Jr. did note that it was the brother-in-law that instigated the fight, but Scott threw the first punch.

Scott will be able to seek a reduced bond at his next hearing.
