Asked why she got in contact she said: "It was for the purpose of the robbery, that's why they were called."
Ms Ahmed was arrested immediately after the robbery. She said her mother told police to arrest her after hearing the robbers say her name.
She said when taken into custody she flushed her phone's sim card down the toilet but it was later found by police. Her phone also had texts on which related to the robbery.
A day or two later she made her disclosure to police about her sister's death but denied anyone had suggested it would in anyway ease her situation with regard to the robbery she later pleaded guilty to.
She has yet to be sentenced for her part in that crime.
Asked to describe why she got involved in the robbery she said:
I think I just absolutely snapped. It was just hard either living the way they wanted me to or living on my own. Both were a struggle.
What did you want to get from it? she was asked by Andrew Edis QC.
I don't really know. I wasn't really thinking properly. I don't know what I was expecting.
Men entered the house, there was shouting I was dragged upstairs, they were searching the house, asking where the money was.
She said three maybe four men were in the house wearing hoods.
I was the one who made contact with them to come over, but as you can see from events I had no control and they turned on me as well.
Giving evidence about the family situation in the run up to the robbery Ms Ahmed said:
I felt I was going down the same path as my sister Shafilea had in terms of going to Pakistan, to be married, it was a lot of pressure. Pressure from my parents with suitors being brought to the house.
Ms Ahmed told how she turned down marriage to one man from Bradford whose family visited the home. She said she knew little about the man apart from her potential suitor had seen her at a wedding. She said she did not want to get married at that time.
I don't even know the person so I wasn't happy with it.
Once she turned down the proposal the family began to talk of Pakistan. She said: "Constantly I was told to go to Pakistan it was just absolutely constant." She said as a result her relationship with her family completely broke down.
Asked to describe her own relationship with her parents Ms Ahmed said it was strained, especially when she went to university, however she said their treatment of her was never as extreme as it was with her sister.
Andrew Edis QC, for the prosecution, went on to ask Ms Ahmed about her involvement in a robbery at her parents home in August 2010. It was during questioning about that offence that she told police about what she says her parents had done to her sister.
Asked why she had spoken out then, she said:
I was in a state of emotional distress. I think at that point I was really struggling with the family situation in the run up to the robbery. It all got too much and it was a relief to be able to tell someone.
Ms Ahmed pleaded guilty to robbery and has since begun therapy and taken religious guidance from an Imam.
A 23-year-old woman has told a court her mother said she must say her sister had run away just a day after she had seen her being killed.
Alesha Ahmed claims she saw her parents suffocate her sister Shafilea at the family home in Warrington, Cheshire in September 2003. It is a claim Iftikhar and Farzana Ahmed both deny.
Alesha Ahmed is giving her third day of evidence at Chester Crown Court. In previous days she has told the jury her sister and her parents regularly clashed over the 17-year-old's increasingly western ways.
The sister murdered teenager Shafilea Ahmed will continue to give evidence in the trial of their parents for her murder today.
Over the last two days Alesha Ahmed has described the escalation of abuse suffered by Shafilea and broke down in tears as she described witnessing her murder.

Asked to describe what she saw her dad carrying, Alesha Ahmed said:
It was the way he was carrying it. It just looked like my sister Shafilea. Just wrapped in something dark, I assume bin bags, with tape.
Then I heard my mum coming upstairs. I just heard a car after a couple of minutes drive away.
Farzana Ahmed then spent the rest of the night in the bedroom with her daughters sleeping in Shafilea's bed.
Asked how her mother appeared she said, "calm."
The court has now adjourned for a break.

Alesha Ahmed then described how her father went for his garage keys, where he kept tools. She then left the room. As she left the room she described her sister on the floor.
Her eyes were still open. She wasn't moving. I went upstairs into the bedroom with my sisters.
Ms Ahmed told the jury she stayed in the room for a couple of minutes then went back downstairs and saw her mum sorting through printed flowery sheets.
Crying she was asked what her parents did after she stopped struggling. She said: "They carried on even when she had stopped struggling."
Edis: "How long for?"
Ms Ahmed: "15 to 20 seconds"
Edis: "How did it appear to you that they were behaving? What did you think about their attitude?"
Ms Ahmed: "Aggresive."
Ms Ahmed described how the other children left the room but she stayed. She said: "I was just frozen in shock. I think it was my dad who pulled her off the settee onto the floor in quite a harsh way."
Edis: "When you were able to see her face once the hands were removed were you able to see the bag?"
Ms Ahmed: "It was pulled out after. I think by my dad when the hands came off. I remember straight after he punched her in the chest for no reason."
