It is extremely out of character for Adam not to return home or communicate with his family and friends and concerns for him are growing as time goes by.
We are urging anyone with any information about Adam’s movements in the early hours of Saturday 28 December 2013 to come forward.
As part of our enquiries we have made two arrests. I would like to stress that it is not clear what involvement, if any, they may or may not have had in relation to Adam so we would ask the public not to speculate.
