India's Mary Kom has overcome a tough test in the form of Tunisia's Maroua Rahali in the women's flyweight division.
A low-scoring opening round ended with Kom sitting on a 2-1 lead. Their respective styles were clashing and that resulted in some messy exchanges.
The Indian began to find her range in the third round and started dipping in and out and landing with both hands.
Kom had built a five-point lead by the third round and went on to seal a 15-6 triumph in the fourth.
