Law said he met with Slaimankhel shortly after Slaimankhel had been released from prison. Slaimankhel told him Mr Yacoub had "snitched". Shortly after that meeting Law met with two Pacific Island or Maori men who asked him to arrange a meeting with Mr Yacoub.
"As long as you don't hurt him and he is going to be okay then I'll help you guys out," Law said he told the men during an interview at Hamilton Police Station.
On the day of the alleged kidnapping Law sent Mr Yacoub text messages pretending to be in Auckland when he was in fact at home in Hamilton.
In the last of those messages Law pretended to be inside the toilet of the Burger King.
"Inside brother where you. Was taking a dump. Phone gonna die G," the text reads.
Mr Yacoub then entered the Burger King.
Law said in the police interview the men had just wanted to talk to Mr Yacoub and convince him to tell the truth to police about pills that had been found in the boot of Slaimankhel's car.
"I didn't know it was going to go to the extent of kidnapping him, I didn't know it was going to go to that," he told detective Laumatia.
"It was a mistake doing it. Look where I am now."
The trial before Justice Christian Whata continues next week.
