A quick-thinking dad saved his young son from tumbling into a canal - only to end up taking the plunge himself.<br /><br />Oleg Cociu, 40, was on holiday with his five-year-old son Matthew in Venice, Italy, last month (July).<br /><br />While walking along a canal, Oleg began swinging Matthew over the edge for fun. Suddenly, he lost his balance - but his quick reflexes kicked in. <br /><br />He managed to push Matthew safely back onto the bank while he himself toppled straight into the water.<br /><br />Oleg, who lives in the Midlands, said: "My wife was filming us and just happened to catch the moment.<br /><br />"I realised I was losing balance, so I focused on making sure Matthew didn’t fall in.<br /><br />"Luckily, no one was hurt, and even my phone survived, thanks to being water-resistant."
