A mother and son were beaten in their home in Dewsbury when two men entered the property and attacked them.
A 30-year-old from Bradford and a 29-year-old from Cleckheaton are being held in relation to the attack where the mother was punched in the face and her son had his nostril split after being struck with a taser.
It is understood that the two attackers gained entry to the Batley Carr property between 3.30pm and 4pm, on Sunday, September 7, through an open side-door and then threatened the victims, demanding money and gold.
During the attack the son was also hit by a glass vase, but was able to fend off the attackers and chase them out of the property.
The 27-year-old was then taken to hospital where he was treated for his injuries.
The two men are also being held on suspicion of possessing a firearm with the intent to cause fear and violence.
Police believe the attack is linked to two separate incidents that saw a grey Volvo, with possible armed passenger, chase a red Audi along Upper Road at around 6.pm on Friday, September 12.
The second incident, the following day, saw armed police being sent to Conway Crescent, around 1.30am, after gunshots were heard being fired, but no arrests were made.
Earlier Detective Constable, Andy Clayton, from Huddersfield CID said the police believed the incidents were a series of targeted attacks, but wanted to reassure residents that he did not think there was a greater risk to the community.
