A second man's been arrested in connection with the fatal shooting of two police officers in Manchester yesterday.

Police say they're holding a 28-year-old on suspicion of conspiracy to commit murder - as well as continuing to question 29 year old Dale Cregan, who was already wanted on suspicion of two earlier murders.

Meanwhile, The Queen's paid tribute to PCs Nicola Hughes and Fiona Bone - calling it a tragic loss of life.
