Christopher Law, former managing director of Alfred McAlpine’s slate business, is charged with three offences

The former managing director of Alfred McAlpine’s slate business has been charged with fraud relating to accounting irregularities found at the division.

Christopher Law has been charged with three separate offences during the period between 1 January 2004 and 26 February 2007. The division’s former sales director Paul Harvey and operations director for its roofing arm, Geraint Roberts, have also each been charged with one offence relating to overstating sales.

Alfred McAlpine reported to the stock market on 26 February 2007 that its internal audit team had uncovered a systematic misrepresentation of production volumes and sales for a number of years by senior managers at Welsh Slate which would lead to a restatement of the 2005 net assets and a reduction in the expected pre-tax profits for 2006.

Lagan has since bought Alfred McAlpine Slate for £31m, while Alfred McAlpine was bought by Carillion for £574m in February.
