the Home Office, and claimed that managers were pressured to pay existing staff overtime rather than creating additional expenditure by recruiting new staff to fill rota gaps. G4S senior executive Peter Neden, speaking to a cross-party government select committee chaired by Yvette Cooper after the revelations, said the profits reported by the BBC did not take account of costs, but refused to disclose Brook House's finances, citing commercial interests. Neden told the committee he was "ashamed" by the abuse revelations and confirmed that G4S was co-operating with a police inquiry.

A report by the National Audit Office published in July 2019 revealed that between 2012 and 2018 G4S made a gross profit of £14.3m (a rate of between 10% and 20% per year) from running the detention centre: the report also highlighted the fact that under the terms of its contract, the company could
