According to Sarup Das Bhalla, Mahima Prakash, supported by evidence of the Bhatt Vahis and an old Assamese journal Padshah Buranji, the Guru one day, while out on chase in a forest near Dhamtan, was arrested by an imperial officer, `Alam Khan Ruhila, and taken to Delhi. The Sikhs arrested along with him included Bhai Daggo. They were, however, all released through the intercession of Kunvar Ram Singh of Jaipur who stood surety for the Guru. Bhai Daggo thereupon came back to Dhamtan while Guru Tegh Bahadur resumed his interrupted journey towards the eastern provinces.
Ten years later, when Guru Tegh Bahadur again passed through Dhamtan, Bhai Daggo served him with devotion. According to Bhai Santokh Singh, Sri Gur Pratap Sura] Granth, the Guru before leaving Dhamtan gave him funds for the construction of a public well and a dharamsala for the travellers. Bhai Daggo, it is said, became selfish and had the well dug in his own fields.
