When some jerk threw a homeless guy’s pet bunny over the Dublin bridge into the Liffey it looked like the rabbit was a goner. But John Byrne, who had been living on the streets since he was 14 , didn’t hesitate in jumping in after his beloved pet, Barney. When John finally got to the poor rabbit he discovered Barney had stopped breathing so he swam to a ledge under the bridge and gave him mouth to mouth. Barney eventually spluttered back to life. As for the evil doer who threw the bunny into the Liffey, he got 4 months detention.
