"They haven't taken any steps. The Karnataka government remained silent. I just want to appeal to everyone that we want justice. Let's punish the culprits and let's arrest them," said Alshi Sharma, Richard's cousin, who gathered at the Jantar Mantar for protest along with several others.
Reports reveal they will also hold a candle march at 6 pm today.
Meanwhile, several others are also protesting at Town Hall in Bangalore.
"We want to convert the case into a homicide one. Case should be dealt with swiftly. We should get justice," Dr Vidyabali Devi, Richard's mother said.
Richrad's family want the accused to be booked and are demanding that his two roommates, prime witness in the case, who left for Bangkok be brought back to the country.
"The fact that the roommates, in the middle of their session, go for a holiday is bizarre...We want the culprits booked, to get the institution responsible and the case to be handed over to the Central Bureau of Investigation," another protestor in Delhi said.
