Younes Kaboul saw his shot cleared off the line by Ryan Shawcross which was soon followed by a disallowed goal for Emmanuel Adebayor, as Spurs' unbeaten run came to an end
Spurs' 12-game unbeaten run came to an end with a 2-1 loss at the Britannia Stadium after Matthew Etherington netted twice against his former club in the first half before the visitors rallied back after the break.
Emmanuel Adebayor slotted home from the spot after Luka Modric was judged to have been brought down in the box, but Tottenham saw Ryan Shawcross clear a Younes Kaboul shot off the line with his arm before the Frenchman was sent off for two bookable offences. Adebayor also had a second strike chalked off for offside.
"We came away with nothing because there's two blatant handballs on the line and Adebayor's two yards onside when the ball's played to him – that's how we've come away with nothing in the end," Redknapp said.
"We were poor first half, and I hold my hand up and say we didn't play well. Second half we battered them and unfortunately a couple of decisions have been completely and utterly wrong. If you watch the TV you'll see it.
"Younes Kaboul gets a booking for telling the ref it was a handball. Then he gets another yellow card at the end there for an innocuous challenge, no worse a challenge than a foul."
Redknapp admitted he could not see the handball offence from the touchline, but after watching highlights on TV, he was incensed that no official saw the incident and confirmed that he spoke to the referee after the game.
"I wondered how he got it off the line," he said, "but if you look at Match of the Day tonight, you'll see the most blatant handball you'll ever see on the goal line.
"I never go and talk to referees after games. I accept defeat, I never complain about refereeing decisions, I've not done it after 30 years, never. But today, I'm afraid he got some badly wrong.
"He obviously hasn't seen them, but when he goes home tonight and sees them, and the linesman, he'll realise when someone's a yard onside, how's he not seen it?"
Redknapp remarked: "What can you do? The referee's not made mistakes because he meant to, he's an honest guy, but today I thought he just had a bad day, and so did the linesman who missed Adebayor being two yards onside.
"[The linesman] will look at it tonight on TV when his wife's making him a bacon sandwich or something, and he'll think 'f*** me, what have I done there today?'"
He added: "To be honest, from the start of the game, I thought the referee wasn't going to give us an awful lot here today."
Pushed as to why he thought that, Redknapp replied: "He was quite enjoying not giving us anything, it was one of those days.
"But they played well first half, take nothing away from them. [Peter] Crouch held the ball up great, they came in and deserved to be up at half-time – no doubt about that at all.
"But second half we changed the way we played and got on top of them and battered them.
"But when you have two handballs on the line and Adebayor's given offside when he's not offside, that's disappointing. That makes a massive difference."
He added: "It's a tough place to come and play, it's not easy. It's always difficult to come here, you've got to deal with what they throw at you, and it was difficult.
"We're not a big side and that was a concern – we knew we'd have problems dealing with set plays today because the make up of my side is small. There's only Kaboul really who is a header of the ball. [William] Gallas is 5'11", after that we struggle.
"We started sloppy, tried to play our way out a few times, lost possession, and everything time the kid on the right [Ryan Shotton] threw the ball into the box, we started to panic.
"They started well. They got after us, they pressed us and it was difficult to live with."
Redknapp took Benoit Assou-Ekotto and Aaron Lennon off at the break for Sebastien Bassong and Jermain Defoe respectively, and confirmed that it was for tactical reasons as he shifted to three at the back, saying he felt Gareth Bale and Kyle Walker – "the two best wing-backs in the country" – would offer more in such a system, and suggested he could play it again in future.
