Numericable has purchased the Wolu TV cablenet in the East of the capital Brussels.
The 10,000 subscriber network, owned by the local municipality, had previously been affiliated to Telenet.
The Liberty Global network had itself bid for Wolu, but Brutélé, which runs the Voo brand, had chosen not to participate.
Numericable said Wolu represented the opportunity to expand in a major Brussels district and strengthen its position as the Number 1 operator.
