Two men pleaded guilty Tuesday to their part in planting a live grenade outside the home of former Liverpool and Scotland star Kenny Dalglish.

The hand grenade was found on the garden wall of Dalglish's house in Southport, Merseyside, northwest England, on July 27, although the incident was not thought to be an attack on Dalglish or his family.

He was not in the house at the time and nobody was injured in the incident, but an army bomb disposal team was called to remove the device safely.

Mark Johnston, 21, and Carl Higgins, 29, admitted at Liverpool Crown Court to conspiring to damage property and being reckless as to whether lives were endangered. They will be sentenced next year.

Two other people, Simon Lewis Ignacio, 28, and Johnston's mother Carol Johnston, 50, have been charged over the incident. They pleaded not guilty and will be tried on February 1.

All three men have been remanded in custody, while Carol Johnston was released on bail.
