Spyware company Datong, which put itself up for sale in February after an approach was made for the business, is to be bought for nearly £7 million.

The Horsforth-based business is being acquired by Seven, parent company of Seven Technologies, based in Lisburn, County Antrim, a specialist surveillance systems business.

Seven has offered 50p per Datong share and is paying £6.92 million for the company in a deal funded by YFM and Seven’s own cash resources.

The deal is conditional upon at least 90 per cent of shareholders accepting and to date 61.5 per cent have accepted. In the year to May 31, 2012, Seven Technologies had revenues of £9.2 million.
