Two men were left battered and bruised after two masked raiders barged into their home.
The men, aged 31 and 32, were attacked with wooden batons as the intruders forced their way into the home and demanded cash.

Both men were taken to hospital for bruises and gashes following the attack, which happened at about 11pm on Friday, although details have only just been released.
