HORRIFYING footage shows the moment a knifeman kicks down a door before stabbing his daughter's father-in-law to death.
Ahmad Alsino, 43, confronted dentist Mohammed Salem Ibrahim, 55, on his own doorstep over a row about wedding gifts for their children.
Alsino, who stabbed Ibrahim four times with a Gino D'Acampo kitchen knife, was tracked across Birmingham by cops before his arrest.
The pair had reportedly fallen out over an argument about gold jewellery given to their children as gifts at their wedding.
Alsino also attacked his daughter's husband, Aram Ibrahim, who was seriously injured but did survive.

Tragically, dentist Mohammed had escaped war-torn Syria for a better life in the UK before his death.
Cops released footage following the killer's movements before and after the horror attack, with the knifeman then seen getting into his car to flee the scene of the crime.
And in dramatic scenes, cops arrested him at gunpoint less than an hour after the stabbing on March 13 this year.
Meanwhile, emergency services had rushed to the murder scene in Castle Vale, but could not save the tragic father-of-five.
The chilling video shows Alsino calmly get into his car, drive to Ibrahim's house and kick at the door aggressively while an unknown person stands behind him.
He then lunges at the person inside - with the doorcam captures him wielding the knife above his head.
Following the brutal ambush, Alsino appears to get back in his car and drive home the way he came before cops swarm him in his cul-de-sac in Northfield.
Armed cops jump from the convoy of cars, holding him at gunpoint, as he lies face down before police put him in handcuffs.
Footage then shows a search of his car by police, where they find a plastic bag containing two knives.
Forensic experts later found Ibrahim's blood on the weapon.

Alsino had reportedly driven his pregnant daughter Lylan to the property where a bitter row broke out with her partner.
He had tried to kick the door down and when Ibrahim came outside he attacked him, with three knife wounds to his chest.
Alsino was found guilty of murder, attempted murder and possession of a knife following a three week trial at Birmingham Crown Court.
Lat week he was jailed for life and ordered to serve a minimum of 26 years after sentencing at the same court.
During sentencing, Judge Simon Drew said: "You took your pregnant daughter to Cadbury Drive to collect some of her belongings from the house where she was living with her husband Aram and the Ibrahim family.
"When Lylan was in the house you waited by the car, angry and upset, but not seeking a confrontation.
"When Mohammed Ibrahim came out of the house he invited you in. That served to inflame matters, your anger increased and you refused his invitation.
"When Lylan subsequently phoned, claiming that she was being assaulted, you believed her and as a result you lost your temper and armed yourself with a knife.
"You went to the door to force your way in in order to get her out but you failed to open it.
"When the door was opened you saw Lylan, Mr Ibrahim and Aram in the front hallway.
"You then launched an unprovoked attack upon Mr Ibrahim and Aram, at first with fists and then using the knife on both of them in a violent frenzy, stabbing each a number of times."
The judge added: "I am satisfied that you must have intended to kill Mohammed when you were stabbing him.
"You knew that you had seriously injured two men but you offered them no assistance and left the scene failing to contact emergency services.
"The whole Ibrahim family, who came to this country to find sanctuary, have been severely affected by your actions on that day."
Ibrahim's daughter said her father had been the victim of a "barbaric and brutal" attack.
She said in a statement: "He was a highly regarded dentist from the Kurdish community.
"He was a pillar of the community. He was not only known for his profession but also for his generosity, kindness and wisdom to anybody who crossed his path."
Detective Inspector Damian Forrest, from West Midlands Police, added: "Alsino's decision to carry and use a knife has resulted in the loss of a father's life.
"His actions, which have rightly been brought to justice, underline the irreversible impact such dangerous decisions can have.
"We know that nothing will ever bring Mr Ibrahim back but we hope this sentence will provide some comfort to his family and friends."
