asked Her Majesty's Government:

On the latest date for which figures are available, how many of the people detained under immigration legislation in Harmondsworth immigration removal centre for removal or deportation at the time of the disturbances had previously served a sentence for a criminal offence; and whether they will provide for each of those persons their nationality and the length of their detention on the date of the disturbance. [HL647]

The number of people detained in Harmondsworth at the time of the disturbance who had previously served a sentence for a criminal offence was 177. It would be at disproportionate cost to look at each individual case in order to provide the information requested relating to nationality and length of detention.
