A High Court jury has heard one of the defendants accused of killing Davender Singh had their hands on the murder weapon while it was wet with blood.
A single fingerprint was found on the handle of a knife allegedly used to stab Mr Singh last August.
His wife and her lover are accused of his murder, but both blame each other.
A fingerprint analyst told the court today that the mark on the handle of the murder weapon is a match for the finger of Gurjinder Singh.
