Freema Agyeman was born in 1979 in London to Ghanaian and Iranian parents.
Ever since a young age, she wanted to become an actress and got her big break in the now cancelled Crossroads as Lola Wise. She later appeared in several episodes of the ITV crime drama, The Bill.
In 2006, Freema played Adeola in the penultimate episode of the second series of Doctor Who, Army of Ghosts. In that her character died.
However, it was confirmed in July 2006 that she would play 23 year old medical Student Martha Jones, the new companion, in the third series of Doctor Who, replacing Billie Piper's Rose Tyler. Agyeman appeared in every episode of the critically acclaimed third series before her character departed following the culmination of her story arc in the series finalé. She subsequently reprised her role as Martha Jones, now a qualified doctor, in three episodes of spin-off series Torchwood, as well as in five episodes of the Fourth Series of Doctor Who.
Following her role as Martha Jones, Agyeman went on to appear in BBC productions of Little Dorrit in which she played tempestuous maid Tattycoram, and Survivors, in which she played Jenny Collins.
In February 2009 Law and Order: UK started airing, which stars Freema Agyeman as Crown Prosecutor Alesha Phillips in all 13 episodes. A second series begins filming in September 2009.
