Two suspects fled the scene and are sought by police. The who males, who were heavily covered in clothing to frustrate identification have been described by police in broad terms. The first suspected bomber is said to appear to be in his mid-20s, standing around six feet tall and having a stocky build.

No estimated age was given for the second man, who was described as standing around 5’10” and having a slim build.

Police have not yet revealed whether there is a known motive for the attack. The Consulate General of India has opened a helpline in the aftermath of the blast, a move which suggests many of the victims may be Indian citizens.
