One Defence Forces officer is going to get a serious talking to later on, we reckon.

RTÉ cameras have been following the progress of the Easter Sunday 1916 Parade, which is taking a 4km route through the streets of Dublin and past some of the key sites of the 1916 Rising.

Oops.

Bet that's the last time he brings his phone to work…
