I'm presuming that this is the title of the news item.
'Ding dong' doesn't actually mean anything. It's an example of onomatopoeia, or in other words, the imitation of a sound - in this case, the sound that a bell makes when it rings. It is also suggestive of foolish behaviour. If you call someone a 'ding dong', it's like calling them an idiot.
The title Ramalinga Ding Dong is a word play on the person's name, and a reference to a famous pop song from the late 50s/early 60s called 'Rama Lama Ding Dong'. And if you look up Rama Lama Ding Dong in the Urban Dictionary, you'll find this:
"Generally describes a rather sad individual, who continually f***s up their life beyond comprehension by repeatedly engaging in reckless juvenile behavior that is consistent with delinquents 10-15 years younger than themselves."
So, what this headline is saying is this - "Look at this funny word! Here is a story about a man with a funny name who did something idiotic."
