Manchester-based Halliwell Landau has acted for AIM-listed client Online Sports & Leisure on the acquisition of a 22% stake in Frank Warren’s boxing promotion and management business Sports Network.

The deal marks another instruction for Halliwell’s AIM practice, which last year acted on almost 10% of all AIM floats. Under the terms of the deal, Online Sports & Leisure picked up the stake for an initial consideration of £2.79m.
