Thug Lewis Jacobs reacted angrily after being told he was to go to prison for harassing a former lover.
As the 28-year-old well-built bully, who is from Sheppey, was heading to the cells, he lashed out and punched the wall forcefully.
Security officials at Maidstone Crown Court were so concerned he might have broken a couple of knuckles they alerted the medical authorities.
He is believed to have broken bones in his right hand.
Earlier, the judge, Recorder Richard Thomas, heard how Jacobs, from Rosemary Avenue, Halfway, had harassed his ex-girlfriend - leaving her "petrified".
Jacobs had made more than 300 calls and texts to his former lover - even though he was in a new relationship.
Prosecutor Ian Foinette told how the couple had been together from June 2017 until June 2018.
He was convicted of harassment by magistrates after hearing how his victim ended the relationship because of "physical abuse " by Jacobs. He was then sent to the crown court for sentencing.
The court heard in March he began making calls to her including making 80 on the 7th and another 100 the following day, then another 42, and 41 on subsequent days, finishing with a series of calls on the 26th and 27th.
Mr Foinette said that among the many threats he made, he also threatened to throw acid at her, shoot a member of her family and new boyfriend, and petrol bomb her home in Strood.
He revealed one of the vile messages read: "Talk you dirty little ****, otherwise I will get people to turn up at your house with a petrol bomb."
She later told police: "I feel petrified because of what he has done and his behaviour. I feel emotionally drained and I feel like just giving up.
"I don't feel safe in my own home. If I go to the shops I have to call someone. I don't understand why he does what he is doing. I also have nightmares."
The prosecutor revealed Jacobs had a previous conviction in 2013 after making threats to slit a child's throat during a row.
Stacey-Lee Holland, defending, said Jacobs had received a threat from the victim's mother who said she was going to "bury him".
"He accepts he snapped and now expresses remorse for the impact it has had on her."
Jacobs, who admitted harassment, was jailed for two-and-a-half-years.
After sentencing, PC Alexander Bailey, of the Medway vulnerability investigation team, said: "Jacob’s constant threats of violence have caused profound distress and fear to the family and left the courts with little choice but to impose a custodial sentence.
"I hope the outcome of this case will encourage anyone who feels they are the victim of harassment to come forward.
"We take this issue extremely seriously and will thoroughly investigate any reports of this nature to ensure victims are safeguarded and provided with the most appropriate advice and support."
