A man, who has filed a complaint against Prime Minister Narendra Modi for allegedly 'insulting' the national flag, today told a Delhi court that he was recently assaulted and warned not to pursue the case.

Complainant Ashish Sharma, who has sought registration of a first information report against the prime minister, recorded the pre-summoning evidence before metropolitan magistrate Snigdha Sarvaria in the complaint.

The court has now fixed the matter for July 30.

'...on May 11, 2016, about mid-night, an attempt to kill took place near my house and I was warned that if I do not stop the complaint, I will soon be dead,' Sharma said.

'On that day (international yoga day), the PM was wearing the tricolour which is the national flag of India. The PM cleaned his face and sweat of his body all over and clean his nose as well, he wiped his face with national flag in front of the world... All the media worldwide as well as Indian Media took photos of the PM insulting our national flag,' Sharma said.

He claimed Modi insulted the flag more than 20 times.

'I strongly believe that PM knows the Constitution of India and the act of insulting the Indian national flag, I am sure that the PM did insult to our national national flag knowingly, willingly and intentionally,' he said.

During the proceedings, Sharma also submitted a list of witnesses to be called for in the case.

The court had on April 6 taken cognisance of the complaint against the prime minister in the case.
