The concert held in memory of London bomb victim Ojara Ikeagwu in Luton on Sunday was a big success according to her sister, Chiowa Lindholm, who organised it.

But it was also a bitter-sweet occasion for the Farley Hill jewellery designer, who has missed her older sibling every day since suicide bombers struck three years ago, killing 52 people.

"We lost my mother when I was very young and my sister was always like a mother to me," Chiowa explained.

Ojara, 55, who lived in Luton, was travelling to her job as a social worker with Hounslow social services when she was caught in the blast between Russell Square and King's Cross.

She was so highly esteemed by Hounslow Council that it established a special excellence award in her name. Her family - including her retired doctor husband and three adult children - are still devastated by her loss.

Chiowa is determined to keep her sister's memory alive, which is why she staged the Love And Hope Charity Event at the University of Bedfordshire's Student Union in Vicarage Street.

The mother-of-three said: "We wanted to celebrate my sister's life but it was very emotional. My brother-in-law and nephews stayed at home but they wanted me to go out and do it, they were supporting me all the way."

Chiowa is now going to put together a 2009 Love and Hope calendar, as well as a DVD of the event to raise even more money for the charities of her choice - the 7th July Assistance Charity and Luton Women's Aid. In addition Radio Diverse presenter Lady Diamond is donating all the proceeds of her single I'm Wishing On A Star.
