"A case of theft has been registered in connection with the matter at Vasant Kunj (south) Police Station and investigation is underway," a senior police official said today.
The incident took place around 7 AM on Friday, when Aftab Khan had taken Zaru for a morning walk in a park close to his residence in Vasant Kunj. The dog spotted a Toyota Innova car moving at a slow pace with a pig inside it, Khan said.
Khan chased the van for a while but failed to note down its registration number, he told police in his complaint.
During investigation, it emerged that a similar car had been earlier spotted in a nearby area where a number of pig theft cases were reported, suggesting the involvement of a gang of cattle thieves in the incident, the official said, adding efforts are being made to nab the accused at the earliest.
Khan and his family also uploaded a video on you tube for people to identify the missing dog in which it can be seen getting a haircut. The family is planning to stick missing posters to help track Zaru at the earliest, he said.
